Script to render in Blender EEVEE with motion blur

eevee_motion_blur's Issues

Addon does not set up view correctly

Just tried your addon like this:

• Open up the default scene
• installed your addon
• rotated / animated the default cube to get some motion
• rendered frame 3

Now it took some time to render, but the result was not visible.

There was a image created called "__motion_blur_temp" (which i can see if a switch an image/render view to that image) but that was not connected anywhere in the compositor (as opposed to what it sounds in the documentation).

The rendered image "__motion_blur_temp" looked ok btw.

Question - Filmic isn't being used

Issue

When I render with Filmic, I get drastically different results on color when using Eevee Motion Blur.

It's because it's set to using Standard RGB color space, regardless if I'm in Filmic.

Standard Base Contrast Reference

F86_motion_blur_ref_standard_CMgamma100

Filmic Base Contrast reference

F86_motion_blur_ref_filmic medium_CMgamma100

Filmic Motion Blur render

F86__motion_blur_sample12_gamma52
Render with Eevee Motion Blur with Filmic settings show that it's.. a standard. It's very similar if not the same to Standard RGB colorspace.

Question

Does this mean that Filmic is not supported yet? Are color spaces supported?

Does the plugin work on particle systems?

I'm getting a "no movement found" message on a scene with lots of movement:
0:00:03 remaining
search ended
max total frame delta is 0px
film exposed movement is 0px
no movement found

however all the movement is in the particle system...?

Bug - Gamma Discrepencies

Issue

When I render normally with Filmic, I have one colour range and contrast - where gamma is set.

When I render with Eevee Motion Blur addon, I have to set the gamma again and the results are clearly not on par with the color management set by Blender.

Question

It seems Gamma is set twice? When and why should I be tuning this?
Why is the gamma value default 0.45?
