TSStatic lets sunlight shine through

#1 Include a *convex* collision mesh.

#2 I have a collision mesh around the shape. The collision mesh itself is transparent.

#3 Show me a picture of your collision mesh.

#4 I am not sure how to post a picture here. I have emailed it to you. The mesh surrounds the a visible object with the same shape.

#5 Oh.. so that's why i was getting the sun shining thru my houses.. i wasn't using a convex collsion mesh...

#6 Your collision mesh is far from convex. Just eyeballing the image I can see a lot of concave edges:


You could just wrap the whole shape in a box for the collision mesh but if you want it to look better you are going to need to use multiple collision meshes (remember: you are limited to 8). Something like this would work:


Something else to keep in mind is that each collision mesh should generally have no more than 20 polygons.

#7 Is that 8 per mesh or 8 total?

#8 8 collision meshes per model

#9 So, are you saying that sunlight will shine through an object if the collision mesh has ANY concavity to it?

#10 Correct
