global illumination results in ignoring specular highlights

I’ve noticed a difference in rendering with and without global illumination. especially noticable with hight glossy metal textures like silver: with GI there is no (or hardly any) specular highlight anymore. Can I solve this problem? thanks, rene

Reply to polygon selection to udim in c4D

never mind, I found the solution to my problem.

The combination metashape / substance painter doesn’t work as far as I can tell. My solution lies in using c4d in between and converting the obj with udims in c4d with arnold. export the new obj and it works in substance painter with only 1 texture set.

polygon selection to udim in c4D

is there a way to convert a polygon selection tag to udim in c4D?

let me clarify: I’ve exported .obj+4texture.jpgs from metashape (in udimformat). when I import this in c4D I get the object with 4 textures and 4 polygon selection tags. When I open the same obj with tex in substance painter I get object with 4 texture sets. And I don’t want that.…

always reflectance in .obj

I import an .obj and it’s colormap comming from metashape, photogrammetry. So it’s only mesh + colortexture. importing this in C4D there is always a reflectance turned on in the material. And with rendering it also has this glossy look. I can turn it off of course but I’m wondering why C4D always turns it on.

What are your thoughts on this?

C4D new zremesher smooths out mesh way too much

zremesh : I’m using a high polycount mesh from metashape in C4D and reduce it to 2% in zremesher. Looks very smooth but the shape is very different, it smooths out the shape. reducing to 2% polygons (triangles in this case) in metashape itself I hardly see any difference in the outlines of the mesh (a sculpture). I can’t find a setting in c4d to…

timeline problem

how come a timeline dopesheet hardly ever shows me animated objects? I only see the animated camera when I open a timeline.

moved from R20 to R25 but material is not the same

After I import an object .obj with material in R20 I switch off reflectance and use only color I get only color. When I do the same in R25 I still get some kind of reflectance. Swapping the material for a new material with just color there is no reflectance. So where does the reflectance in the original material come from? and more…
