Caustics by Imagemap bumps
Posted: Tue Jun 16, 2020 10:51 am
Hi all,
I'm new to LuxCoreRender, and it's awesome!
I obtain really beautiful caustics by applying a texture (for example Blender Clouds) as the bump input in a face of an otherwise clear window. I would like to use a custom image map instead of the available textures as bump map. So I loaded an image with the ImageMap node, and connected it to the Bump input, but this doesn't work. Attached the blend file.
Any idea to get this work?
Thank you!
