Missing Triangles For Mesh Problem

[SweetBloxxer714]

I’ve just created a stone wall from Blender but the imported mesh to Roblox has missing triangles. I tried checking off “inside” from “Recalculating Normals” but the mesh still has the triangles missing. How do I fix this problem?

I’m new to Blender so thanks in advance for future help!

try exporting as obj first instead of fbx, this sometimes can fix some problems
