Hi, Sorry, life in the way here again. As mentioned I am going about this sort of backwards.  I have an older merchant resource set of maps for a 3D figure, there are allot of shadows where there should be none and other bits that don't look very good.  So I smoothed out the diffuse to blur it out and repaired all the shadowed areas (Imagine a torse, ab area, one side has no shadows, clean, nice.  The other side looks like the photo was taken in a room where the light casts a shadow on that other side. it was a mess.  It's fixed now.   But then I needed to go back in and put in all the detail info like pores but I decided to work on the specular / bump so I could work in black and white.  What I want to do is bake that info into the diffuse map in hopes of 3DCoat generating a clean Normal map.  I tried generating one with the old diffuse info and it was a pixelated mess on parts and other parts looked just OK.   I working with a low poly imported OBJ.  If I need to make it into a high poly OBJ , not sure how to go about doing that.  It would be nice to have an option to upscale it within 3DCoat.   Again, sorry for the late reply.  LIFE!  

Evil_Weasel  Hi! A little report on Modeling/Retopo room. There is very often used command, to toggle low poly wireframe display ON/OFF, in 3ds Max we have it on F4, and I use it all the time. In Coat it is hidden in that drop down list, and when you hover over those commands, it shows standard tooltip - press END to assign shortcut, but it doesn't work for those commands in the list. Instead it creates shortcut for "choose checker style" which basically does nothing   So... You can't have a shortcut for Wireframe, which is very annoying in poly modeling.  

seems fine , cant seem to replicate , this is 99% decimation from 5.8 million

i just tried a tree mesh i have and didnt get any decimation errors..  ive got a few birch tree ones ill try them

It does happen with pretty much any object but not all.They all come from reality capture but as soon as they are voxelised it shouldnt really matter. I'll try a few other meshes and see how common it is.

I tried the same thing with photogrammetry objects. I didn't see any glitches. More steps are needed. Perhaps there's a problem with your specific object.

Hello! Upload the model directly to the Retopology room and create a new UV map.

Hi there everyone! I hope you are doing fine.   I am having some trouble regarding a poly group UV I created by accident.  I modeled some object in the Modelling Room. Accidentally I did an "AUTO MAP" command and it created seams and did the unwrapping. What I am trying to do now is to erase the UV associated to this polygroup, as I wanted to do it by hand. I understand that if the geo was created elsewhere (Modo, 3DsMax, Blender...), the UV map can be deleted there before bringing it to 3DC. However, is there a way of erasing UV maps associated with geometry created in 3DCoat directly?  Thanks for the help everyone!

Since v.08 3DC is compatible with RS 2.0. Are you using that version or a later one ? 3DCoat-2025-08 Thu Jun 19 08:51:04 2025 - Initial (first) loading speed issues fixed (related to Python modules loading). - RealityScan 2.0 is used as the default photogrammetry engine

Same problem as MkIII_X, even setting the instal path to realityscan doesn't really seem to do anything so i'll use the standalone in the meantime but it's a bit of a bummer to not be able to use realityscan in 3dcoat

Alright, so you need a very high res mesh around 100 million polys. Then right click and export as... When dialog opens up set it 95 percent. It should not matter if you export from a volume or a surface. But thats really it. And it works perfectly if I use the top bar menu to do the same. Then I will export the mesh without decimating.

@Toxo Hello! Please describe the steps you take to get the glitches after decimation. I'll try to replicate it.

I think it's a bit to big to share here 3.5 GB. It happens with all large photogrammetry meshes, pretty much. But only in the decimate dialog I get when I export. If I do it inside of 3Dcoat it works fine.
