Hi, Looking for someone who can help or has had a similar problem. I am working with sculptris to create concepts, sculptris exports in a .obj format but will not import to unity, i get a blank mesh with no verts or tries so essentially no model. I can import to blender and have tried messing with normals, weight painting, adding normal maps, texture maps, bump maps. I have also tried exporting the model from blender in .obj .fbx and .blend (.fbx works for models i made in blender but not for models i imported from sculptris). Thanks for you time any help would be great.
My guess is most probably that your mesh is too big. Sculptris has a polygon reduction tool. Try that. You need to stay below 65.000 tris. Thats the biggest allowed size. Its a hardware limit of your graphics card. Everything bigger has to be split into smaller parts.
Besides that, Sculptris meshes are not meant to be used in Unity directly. Sculp-modeling creates biiig meshes as you found out now. But even with polygon reduction: the by sculpting created topology is very bad for animations. And it is also bad for static meshes. You will have ways less tris and a cleaner meshflow when you model your mesh directly in a polygon modeling app like Blender. My advice in case that you cannot live without Sculptris for modeling is to use the Sculptris mesh as a base to model the game mesh from.
I do understand the issue with the high poly count and will try the reduction. Are you saying 65,000 tri’s is all unity will allow? I am planing on using blender for my game models and animations. I was just hoping to make the concepts by sculpting and painting in sculptris, then porting to my game world in unity to see if i like how the model or concept fits in with my world before I spend more time on it. It’s very easy to make quick concepts in sculptris and use image overlay to recreate in blender. I would like to be able to incorporate it into my workflow.
I know this is old but, Unity only allows 65,000 tris per mesh. Go to the options in Sculptris (I am using Alpha 6) and there should be an option unchecked about exporting the mesh’s normals. That’s what you need, I came across this is trying to solve my problem. Only have the mesh is being imported properly. Half is imported fine and the other is dotted like a noise map.
