future-is-bright's Issues

DirectX Problems

i have DirectX 12 but its not working for "future is bright" should i downgrade it ro DirectX 11 or 3D?

VoxelGPUCascaded - Heavy, erroneous shadows on the tops of Unions

RBXL for repro.

Certain Map always crashes on ShadowMap

I was digging through old place files to try out this. This map has crashed no matter what when switching to ShadowMap. Myself and a friend both tested. This should be unrelated to #2 as we both are on Intel CPUs. Place file attached.
PBSTTZ.zip

My specs:
Windows 10 Home, Intel Core i7, 8Gb RAM, Nvidia 960M
His specs:
i5 with 6 GB RAM & intel HD 4000, 8Gb RAM

Weird lines when zoomed out

Not sure if it's my graphics card, or the actual prototype, but weird lines appeared when I moved my camera angle furthest away from me possible.

Weird "big black pixel" artifacts and other lighting glitches happening in my game

When I tested out one of my Groups alleys and tested it in the new lighting, there was so many weird glitches happening to the lighting in both VoxelGPUCascaded and ShadowMap. In VoxelCPU it is normal and runs perfectly fine. One of them was that the normal "white" lighting above the lanes wasn't lighting up but the black lights show up fine. Here is a video of the glitches I was encountering: https://www.youtube.com/watch?v=zOCIVgon4F4

Place not loading up

When the studio opens up its fine but when i try to enter a place or even make a new baseplate the place window becomes completely white while the start page is fine. It doesn't crash just white screen on the game window.

I have windows 10, i5 core and a GTX 750 ti.

No way to disable or adjust the transition speed of HDR on the current prototype

SurfaceLight issues

Odd pixels appear around the border when I have a SurfaceLight in a part. When closer to the part, the pixels vanish, but they are visible from far away.

Enabling Shadows on the SurfaceLight removes these pixels.

But having shadows on enabled, I changed the light to face the bottom, and this is what happens:

I put the glitched part next to a row of parts and this happens:

DOESN'T EVEN LOAD THE GRAPHICS

It just loads the current screen

Poor Rendering with New Engine

Although I do believe the new rendering can be quite delightful, there are some issues concerning switching over to the new engine. I have attached before and after images of my personal fan builds, with adjusted lighting in the new and old lighting engines. The issues appear to be quite distinct.

lighting through transparent objects

i had a spotlight from some train lights and made the spotlight do shadows from objects, but i thought that maybe it will go through transparent objects a little so i put a block in front of it with 0.5 transparency to test if transparent objects would let a little light through it... but it acted like it was a solid object and not transparent (this is with shadowmap btw)

When trying to use "shadow map" Roblox studio crashes

Can't open up a place or start a new pne

It says it is loading and when it is done loaded, I am still on the start page :|

(Question) is the "bloom" feature going to be added? i am only wondering this because in the video where "the future is bright" was represented had a bloom effect.

places not loading up even though i have the right graphics card

Roblox studio will not work even though i have DirectX 11.1

Can't open RobloxStudioBeta.exe

I download the zip, open the folder, and doubleclick RobloxStudioBeta.exe, for a second something is loading but then it disappears and a popup says that it can't proceed because "Qt5Gui.dll was not found". It proceeds to tell me to try reinstalling the program. Once I click okay, the same popups come up for Qt5Widgets.dll, Qt5Core.dll, and Qt5Network.dll. I have tried downloading the zip again but this keeps happening. I can easily find these dll files on my own, I'm not sure why it's saying they aren't there.

some issues I've found that involve LoD and crashing

First bug:
When testing performance by generating a 20x20 square of point light parts, I found that the closer I got to the center, some lights would stop rendering despite the fact I was close to them and when I got further away, they appeared again. Here's an image of what happened

Second bug:
I saw that the shadowmap was no longer rendering any shadows and that there was some random ominous incredibly large shadow that disappeared depending on camera angle. I tried to fix this by going from Shadowmap to VoxelCPU and back, but all that did was crash when I tried to go back to Shadowmap.

ShadowMap - Ambient and OutdoorAmbient do not behave as expected

The two properties seem to mix together to form one lighting color. As a result, the shadow color cannot be changed.

How do I set it up??

Seriously.. How? xD

Shadows don't display with constraints

As you can see the rope constraint I am using is not being shown with the shadow.

Windows 7 shadowmap support.(Fixed, dont mind this)

Shadowmap does not work on windows 7, we have done tests with windows 10 and it works fine with same specs.

I cant use shadowmap on windows 7 myself, as it crashs instantly.

my specs are:
gtx 1060 6gb
amd fx 8350 4.0ghz
windows 7

Please fix this.

Quote, "Future is bright" Not working ::)

This was a COMPLETE WASTE OF TIME it doesn't work at all. First, starting roblox studio, loading, loaded everything functions every little thing works but, the screen is still stuck on the menu. I want this to be fixed right now otherwise I'll be stuck in a white screen forever

Custom Studio isnt working

Hello! I seem to be the only one having this issue. Or maybe not, but so far no one has been able to help me.
(Fastfoward after downloading the zip file)
I extract the folder into Documents.
I then open up RobloxStudioBeta.exe
I select new baseplate.
White screen occupies the place where the whole studio should be.
Ive tried to uninstall and reinstall it numerous times, but it still has the white screen. I cant ever get it to work. It might be my windows, but I have windows 10 and im pretty sure its supposed to work with that.
I also then tried to extract it to different files, but it still never works.

Any help please? It will be very much appreciated, and thanks in advance.

Setting angle of Spotlights to zero with shadows on in ShadowMap messes up rendering

It's kinda hard to explain what this does, so I'm just going to drop a gif by here.
This issue happens with lights of all colors and also with SurfaceLights

Specular Highlights (?) Showing from Light Source Behind a wall

The light this is coming from is inside the building. This doesn't seem like intended behavior and I don't know if it's known, so I'm posting it here. (This is ShadowMap by the way)

Crash upon selecting ShadowMap lighting mode

Specs:
Processor - AMD FX-6300 Six-core
Graphics card - Nvidia GTX 1050 Ti
8gb DDR4 RAM
Windows 7 Ultimate

Studio crashes upon selecting the "ShadowMap" lighting mode. Selecting GPUCascaded works fine. Crashes on any map, no matter where you are, how many programs you have open, etc. I have a DX12-compatible card, 4GB VRAM, and Windows 7 which meets the criteria on the github page.

This really isn't an issue but a solution.

I found a way to make it work on DirectX 10. Search on Start, dxcpl. Click edit list and add the future is bright into there and click ok. Do not exit yet, check Force WARP and then it will start working. It will be a little bit laggy. But this is a solution until he adds it for DirectX 10, which might take a while

Turning off GlobalShadows after switching to ShadowMap breaks the shadows

After messing around for a while, I found that GlobalShadows affects how shadows are made.

Shadow map works on windows 10, but will not work on windows 7, ive tested both operating systems and i just cannot get it to work on windows 7

LightInfluence acting odd - I think?

This seems like unwanted activity with LightInfluence, but when I set all Ambients to 0, even though there is environmental lighting, the particle practically disappears.

The color is virtually the same at night, you can just see it a little better cause it's darker in the background.

Lighting artifacts, spazzing, and overall shading glitches

I'm guessing this is already known, but I'm gonna put it here anyways.
This video should explain it much better.
YouTube Video
Shading bugs, lighting has a seizure, and there are lighting artifacts/lines/less-rendered areas all around.
Do note - this only seems to occur for me with SurfaceLights and SpotLights. PointLights don't spaz out like this.

ShadowMap - Shadow-casting lights spontaneously stop casting shadows

Enabling/disabling shadows or the entire light source doesn't seem to fix it. The lights usually stop working after waiting a long time.

Switching to shadowmap causes instant crash

Whenever I try enabling the shadowmap Lighting mode, studio instantly crashes for me. No lag, nothing. Just instantly crashes with the regular crash dialog box.

PC Specs:

Windows 7 64 bit OS
Intel i3 CPU
4GB RAM

'Graphics drivers seem to be too old'?

I tried running this custom build of studio to mess around with the prototype lighting system to see what features it had.

But when I attempt to open an empty baseplate or terrain baseplate, I see this in the output:

21:29:51.361 - Your graphics drivers seem to be too old for Roblox to use.

I am using integrated graphics on an intel i3 (Which DO support DirectX11). I am able to run ROBLOX at full quality graphics no problem.

Future Is Bright link are totally not respectfull.

RACIST LINK they only have limited time for download, please respect people with slow connection to donwload the link without limited time address.

DirectX 12 Compatibility

How can I run it with DirectX 12? It says I need DirectX 11 when I launch the studio in the donwload. What can I do?

No way to disable shadows on specific parts

VoxelGPUCascaded application - these trees are horrendous

ShadowMap application - ViewModels shouldn't have shadows at all

Support Direct3D 10/10.1

I've been proven wrong before and now the Roblox Studio says my system isn't compatable to DirectX11. This can be a problem I don't know what I can do about it

Shadowmap bug.

When moving around in a light, the shadow wont update, just kinda freezes until i stop moving again.

ShadowMap - SpotLight with shadows enabled causes artifacts when near parts

Place Opening Visibility

Everything works fine, except for actually being able to see the place... can still change settings and properties.

ShadowMap buffer doesn't get cleared when GlobalShadows is set to false.

If you turn off GlobalShadows while in ShadowMap mode, the most recently rendered shadow map stays in the buffer. It looks really weird when moving the camera around.

ShadowMap - Shadows get warped at different angles of incidence

This screenshot consists of a SpotLight coming directly from the camera. Notice how the ironsights on the weapon get their shadow duplicated due to warping on each wall.

lol

i hurt myself

Shadowmap - SurfaceLights with Shadows Enabled Bug

^ with shadows enabled

^ with shadows disabled

not sure if this is a bug or its from my end but ill post it anyway

Artifacts with surface lights and ShadowMap type lighting

I've posted a picture as an example. There's strange artifacts like "cuts" in the light casted upon. In this example I have a surface light on each surface except for the ends with shadows enabled and and angle kept at 90.

neon is a bit bright

i went onto my night time test game with neon lighting and it is a bit bright for what i use it for https://images.discordapp.net/attachments/336864753743822870/338511315112951818/RobloxScreenShot20170723_123642632.png?width=946&height=470

Compatibility on Mac/OX?

Is there going to be a release on Mac/OX?

Setting LightingMode to ShadowMap with GlobalShadows off crashes Roblox.

I ran into this issue while I was trying to enable shadow maps in crossroads, since the place doesn't have GlobalShadows enabled.
