OctaneRender™ 2019.2 XB2 [latest 2019.2.x] Tweet

[mojave]

Dear all,

We are happy to share our second experimental build of Octane 2019.2 As with all experimental software please do not use this for production purposes.

This release is mostly a maintenance update. There are still some outstanding issues at this point, but we are making good progress for more fixes to arrive soon.

Please also ensure that you have a NVIDIA driver version 419.x or newer.

Changes since OctaneRender 2019.2 XB1:

New features:

• Replaced pin to enable RTX from the kernel settings with a flag in the device settings that enables RTX persistently for all devices.
• New relase flag disableRtx to completely disable RTX even if enabled in the device settings.

Bugfixes:

• Displacement: Fixed unnecessary updates in some more scenarios when using vertex displacement.
• Geometry: Fixed ghosting issue when modifying instance positions and RTX was enabled.
• Geometry: Fixed lack of motion blur for some objects when RTX was enabled.
• Geometry: Fixed issue that would cause some objects to appear transparent when using an environment medium when RTX was eanbled.
• Lua: Fixed denoise devices always matching the devices using priority.
• Material: Fixed issue with glossy materials which would always trigger a full update.
• Material: Fixed shared toon materials only rendering correctly on one object, the rest rendered black.
• Material: Fixed toon outline always rendering black.
• Material: Fixed texture projections other than mesh uv not working with scattering and absorption.
• Material: Fixed dirt texture being ignored for layered materials.
• Material: Fixed universal material pins to specify transmission type.
• Material: Fixed universal material layer with thin wall and single sided geometry behavior.
• Network Render: Fixed network rendering when RTX was enabled in render slaves.
• Picking: Fixed picking when upsampling was enabled.
• Picking: Fixed error after using mesh or material picking when RTX was enabled.
• Render Pass: Fixed layered material diffuse direct contribution being output into the reflection direct pass.
• Render Pass: Fixed smooth normals when geometric and vertex normals would be in opposite hemispheres.
• Stability: Fixed crash when using texture displacement and accurate rounded edges.
• Stability: Fixed CUDA crash when using AI light and RTX primitives.
• Stability: Fixed CUDA crash with meshes with more than one material and emission wen RTX was enabled.
• Stability: Fixed CUDA crash in scene with emission and various geometry types when RTX was enabled.
• Stability: Fixed crash while loading some meshes with polygons of different sizes when RTX was enabled.
• UI: Fixed issue with displaying and updating the device priority flag in the device settings.
• UI: Fixed memory tracking when RTX was enabled.

Known bugs:

• Scenes that contain not just triangles can be slower when RTX mode is enabled.
• Dirt texture applied to triangles will evaluate as black when RTX mode is enabled.
• Round edges will not be evaluated when using accurate mode and RTX mode is enabled.

Toggling fake shadow doesnt update render:

1. Right click and render the universal material
2. Toggle fake shadows on. NOTE: nothing updates in the render
3. Stop the render
4. Right click and render the universal material. NOTE: Now the render updates


EDIT: Another test... If you set coating color to white, toggling fake shadows works in real time, but the render is wrong until you stop and restart it

Universal transmission bug. When specular and transmission are 0, and you add coating, the material becomes transparent

1. Right click and render the universal material. NOTE: Its transparent, which is incorrect
2. Set coating color to 0 (black). NOTE: The material is now black

No MAC installers?

OSX and Linux are coming but some extra work is still required until we can share them.

Thanks for reporting, this is now fixed.

Hi,

Fake shadow should not have any effect on diffusely transmissive material, it's only for specular materials. This means the first bug you have reported is actually a correct behavior, I have only avoided a shader recompilation in this case as it can be quite an expensive operation for plugins, as it's basically meaningless to rebuild the shader if it doesn't change the rendering.

However, fake shadow on diffuse transmission + coating should not be affecting the rendering of the material, so that means your second bug is a real bug, and I have fixed it.

Thanks for reporting.

Thanks for checking it out Wallace. You say the first is not a bug, but I want to make sure you noticed that the material changes in appearance AFTER you restart (step 4). So if toggling fake shadows should do nothing (as it does in step 2), then step 4 is still incorrect.

In this update, my castle scene does not render at all. Including switched off rtx. As soon as I start the render, a crash occurs.
