Here I set the intensity 0, but the water pattern texture is still visible. At intensity 100 the same look.
EDIT: in CPU mode the intensity works. So, it’s a GPU mode bug.
Hello,
Thank you for reporting this!
This is a bug and it has been reported in our system.
I see you have found a workaround with Affect Diffuse option.
Regarding you second issue, could you please change the resize option(V-Ray Asset Editor > Settings > Render Parameters > GPU Textures > Resize) to Full-size textures.
If this does not fix the issue, could you please share a scene were the issue is reproducible so we can investigate in detail?
If this is alright, please use the Pack Project option (V-Ray > Pack Project) and send us the zip file at support@chaosgroup.com
Hi Micha,
Have you tried setting the intensity with the latest stable build?
It seems to work as expected for me.

This occurs because the texture that emits light is rescaled for optimization purposes and in this specific case when Directionality is set to 1 this becomes visible.
This has been brought to the attention of our developers so a possible future optimization can be discussed.
Nevertheless, there is a really quick workaround that provides a decent result.
This would be to use a Blend material with Emissive material as coating and a caustics transparency texture.
To do this first add a new Blend material then add the tiles of your pool as a Base Material.
Create an Emissive material and add a black and white texture representing the caustics in the texture slot.
Add the newly created Emissive caustic material as a Coat on the blend material.
And you will now have caustics material.
I have attached an example scene:
Caustics_material.zip (1.02 MB)
Thank you for the workaround.
I’m very curious for the future optimization since for example at the last project I need the projected pattern over different objects with different materials, also some parts shadowed by others and without pattern at the backside of the objects.
A fix for the texture resolution issue will be available in the next update.
