Decals so far works in rendered mode, but when switch to Raytraced the decal completely disappears. I hope there is a solution, I appreciate your time and efforts!!
Just to make sure that everything is in order on your side please make sure that you don’t have custom changes in your Raytraced settings: Tools > Options > Views > Raytraced > Restore Defaults
The issue was the backface settings, i had “single color for all backfaces” selected. Once I selected as you advised to restore to defaults, it worked. Thank you Nathan, I appreciate your help.
I hade the same kind of problem. But when i closed and started rhino again it the picture started to show in the raytraced image. Cycles seems a little bit buggy to me…
If i assign several materials to an object, cycles renders the decales and the materials incorrectly. Everything is correct in the Render Viewport, as in the render mode. Assigning multiple mapping channels also confuses cycle. vray renders correctly via both CPU and GPU. is there a solution. thank you
There are the Pictures
This is in V6 and also in WIP
The first is Cycle (RaytracedViewport, the second RenderViewport
There’s some decal work for Cycles going on as https://mcneel.myjetbrains.com/youtrack/issue/RH-45742 but what you show may be due to some other things I’ve filed regarding sub-object texture mapping. Please send me the file with the textures if you can and I’ll add it to the open bug I think this is about. You can email tech@mcneel.com to my attention or private message here on the forum. Thanks.
This looks like a decal on an object that has multiple materials applied. The texture baker currently in use fails in this case. As @BrianJ mentions I am working on native decal support. In a couple of weeks it should all be much better and faster.
Hi, I still have this problem randomly… when I switch materials under the decals they sometimes disappear in cycles and rendered and I don’t get them back. It really drives me nuts. I don’t think ditching the decal function for a material is a good solution. I mean you built this feature for a purpose, right?
What else can I do?
It’s a physical mat with a png decal with alpha activated. If that helps.
The SR didn’t help.
While using Raytraced changing the material is known to “lose” the decals. At that point you have to toggle away to say Wireframe, then back to Raytraced. But the decals should still be on the object.
I tried switching back to wireframe but it didn’t work. Changing the underlying mat to PBR seems to work for now. But that also makes it impossible to use custom mats (not PBRs) as background.
