Import .dds in sandbox : wrong render

[Florent Glibert]

 

Hello everyone

 

Babylon sandbox

For the moment, I try to get same render in 3ds max and babylon sandbox with pbr material and environment map.

If I put a .dds environment in 3ds max. The exporter exports correctly my .dds and after a drag and drop to babylon sandbox, I have a good render.

But if I want to change my .dds by another in babylon sandbox, the roughness on my material doesn't work anymore. While the .env works correctly, the render changes and the material responds well to environment.

It’s the same issue for .babylon or .gltf.

export .babylon with .dds environment.

Changing .dds environment with another .dds on babylon sandbox.

Changing .dds environment with .env on babylon sandbox.

 

Is that possible to change the .dds to see modification on babylon sandox? It’s simpler instead of always returning on 3ds max, changing my environment map and re-exporting.

 

 

 

 

The exporter .env.

The “generate .env texture” works only if the .dds is exported from 3ds max. It doesn’t work, if I change the .dds on babylon sandbox. It’s the same with an .gltf.

For a better workflow, is that possible to add “generate .env texture” directly on the exporter (3ds max, maya, …)?

 

 

Thanks for your time and help.

The dds file needs to be preprocessed to ensure that DDS will work accurately with roughness:

This might help you generating the DDS.

About the sandbox you can load dds by drag drop or through the inspector.
