My votes: V-Ray for 3ds Max

the current volumetric material options in vray only support 2d textures. This is problematic for controlling (for example) cracks running through ice, or generally any changes to density or colour inside the volume. vrayenvfog supports 3d maps, b...

Straight forward render element to get The translucent of all objects at once.

The title is self-explanatory. I use it frequently in my workflow, and it would save a lot of clicks (open Render Settings > scroll down to "Fit resolution to VFB" > close Render Settings). Thank you

fast work

After generating a Gaussian Splat it would be great if we could have the option to add lights outside or inside the Gaussian Splat. This way there is more flexibility to highlight parts or change the overall look and feeling of the splat

To speed up the rendering using Gaussian Splats it would be great if we can render using a velocity pass. This way we can add camera motion blur later in post.

Please add the same Toon Edges Override as the Maya version to the 3dsMax version of Toon Mtl. https://docs.chaos.com/display/VMAYA/VRayToonMtl

Sometimes I use multiple maps in multisubTex and when its time to connect the normals, the auto gamma its not adjusted, this could be very handy to have rather to apply it manually to each texture

VrayLightMtl has been limited since very long time, hope you can delete Direct Illumination restriction soon

Similar to Corona camera where we can have environment overrides, this way, we can have more control per camera instead of having a global configuration and save changes for each camera in state sets or Pulze
