• env_emits_GI is true by default.

Vray2SideMtl材质的透明度与ER不一致

GI cache最终密度应与bucket size无关

Initialize EH_Light intensity to 1

支持中文版

提供官方中文版

迁移到VS2015

提供自己的灯光系统

提供渲染器自己的灯光物体类型

ElaraLight, ElaraSun, ElaraSky, ElaraIES.

支持毛发材质

添加毛发材质的支持

AOV对gamma, exposure开关支持的问题

AOV对gamma, exposure开关支持的问题

Max插件渲染过程中不显示已用时间

已用时间一直是0

支持Houdini

支持Houdini插件

ER不支持3dsmax spotlight面板中的decay type参数

支持SketchUp

支持Elara for SketchUp

vrayblend材质与elara不一致

提供中文文档和代码注释

EH_convert_native_arguments memory leaks

EH_utf16_to_utf8
EH_convert_native_arguments

ies_filename为空时不创建light_filter

ies_filename为空或长度为0时，不创建std_light_filter，用于创建纯点光源

Vray的4种基本BRDF均支持各向异性，Elara需要同步

Elara for Katana

支持Katana的插件

Performance improvement for writing mesh using Home API

Writing large meshes takes significant amount of time.

Color Correction based on 3D LUT

Add dongle ID to apply manager's return value

支持烘焙spherical harmonics

改进曝光控制的Shadow算法

现有Shadow算法并不难很好的提高图像的对比度。

开源的GUI例程

提供开源的GUI例程，便于：

1. 用户学习、集成Elara技术
2. 直观的调试渲染效果、后期参数

Fix stereo support in cubemap/spherical camera

Fix stereo support in cubemap/spherical camera.

Currently the algorithm is using a fixed right vector, which is incorrect for virtual reality rendering.

The correct way is to compute a different right vector for each ray based on up vector.

Expose spotlight to Home API

Add EH_LIGHT_SPOT type.

Use size[0] as spread, use size[1] as deltaangle.

User Orientation

Allow user to customize:

• Handedness
• Wiring order
• Up direction
• Environment orientation

ESS Parser Standalone

• A standalone application/DSO to parse and analyze ESS files.
• Free to use, no extra license is needed.
• API to extract all referenced resources including texture maps and IES files.

加速结构遇到INF

Optimize scene export performance of MAX plugin

• Profile scene exporting performance for large MAX scenes.
• Optimize hotspots.

Support simple directional map as an AOV

For this map， use rgba format， the rgb is the direction of the point's main direction. While the a is the percentage of the irradiance of this direction compare to the whole hemisphere

Vray折射glossiness效果与Elara差异过大

Comprehensive scene checker in Elara core

The scene check should play an important role in checking invalid scene data, and warning potential performance issues, by checking:

• Out-of-range indices in polygon meshes.
• NaNs, Infs, Big numbers in polygon mesh data.
• Instance matrix has NaNs, Infs, Big numbers.
• Excessive amount of overlapped geometry.
• Accel falls to very poor performance.
• Print global accel bbox.
• De-generated triangles.
• Highly directional HDR as environment.
• Skylight used in interior scene rendering.
• GI cache consumes too much memory.
• Excessive rays per sample.
• Intensive use of non-opaque objects/materials.
• Intensive use of IES lights.
• Intensive use of mesh lights or emissive objects.
• Too many textured lights.
• Point light uses more than one sample.
• Light sample is too low for area lights.
• Non-energy-conserving shaders.
• Excessive use of specular (glossy) and reflection (mirror) at the same time.
• Non-tiled/mipped textures.
• Separate specular/diffuse AOVs are required.
• Per-object/light time cost profile.

自动曝光API

API和MAX插件支持

Vray材质diffuse、glossy通道强度分配与Elara不一致

典型情况：当VRay材质关闭Fresnel时，如果glossy开成纯白（255,255,255），diffuse通道将不产生作用
Elara在这个情况下diffuse还是有一定的比例
