volume on top of two meshes

[thomaslisle1309]

Hi i have a volume with some displavement.  its on top of several meshes but it only treats the first one normally the others all change the colour of the volume making it go dark.   I cant work out whats going on   is there a way to fix this cheers Thomas

Can you screengrab your geo/settings/shaders/renders, please? Does increasing volume_ray_depth help?

[thomaslisle1309]

hi Lee thanks for getting back to me   increasing  ray depth doesn't make any difference  just 1 diffuse ray renders the same as 5 on every ray depth item !    I have tried hundreds of options cant seem to get around it    I have two planes in the background and a cube right under the volume.   the volume should be bright red 

many thanks kind regards

It looks like the way the circular ramp is being used in the volume_displacement is causing it to look like this. I would maybe use a camera_projection with the circular ramp.

Also, the HDR textures seem to be mixed up. The Sven texture is in the skydome_light.

hi oh i see just deleting the ramp and it gets rid of the anomaly.   I will try a camera projection  UV map  later today when I have a moment.  great ! thanks 

re HDR. I have only one HDR map attached to one skydome and no texture called Sven ?   could you elaborate please as I dont understand    many thanks thomas

Ah, apologies. Must have been a mix up my end then.
