I looks like you are using 3ds Max. Try Probooleans. http://docs.autodesk.com/3DSMAX/16/ENU/3ds-Max-Help/files/GUID-7621338C-661E-4A8E-9CC5-87DC8420D51A.htm
I would recommend baking in Substance Painter. I'm pretty sure 3dsMax doesn't use the same tangent basis as SP (Mikkt) so you will likely get normal artefacts and seams.
Thanks iadagraca :) Spacedraw is getting better and I begin to know it quiet well now. For the pure poly modeling part I go faster on my phone than on 3DSMax for many operations ;)
Most likely this is the Ambient set to black. Look for it in the Rendering menu, under Environment. http://download.autodesk.com/us/3dsmax/2012help/files/GUID-EF33AEB1-44BE-403E-B4CC-3C29495988C-2396.htm
now that I think , my rock can be rotated in many directions , so how can I chose each time a direction ? May be in 3dsmax is there a way to apply a shader and bake that as snow?
OSD hotkey won't work on 3dsmax and zbrush, dunno why. Also tries keypose and showoff not working on max http://sumtips.com/2012/05/show-key-press-mouse-click-on-screen.html
If it was flipped wouldn't it not show the texture at all? Also, do you know if blender has the functionality to "show" if UV's are flipped (like in 3dsmax, where it would colour the island red instead of blue)?
Depending on what program you're using and how your rig is set up there are quite a few different ways to tackle this. I've done this exact same thing in 3dsmax using animation layers.
Okay! Got around to do some sculpting and coloring and just had to test out the diffuse and normalmap in 3dsmax, heres what i got so far, without any of the other subtools:
I think this might be a bug in FBX export in 3dsmax 2015, prior to export, you should convert your mesh to editable mesh, then back to editable poly. If you export it then it should be ok.
