Hi. I'm trying to track down a clipping problem, but am unable to isolate it such that I can either a) fix it in our code or b) send over a small project to demonstrate the behavior. What's happening is this:

1. We create a map entity with ent_create().

2. Shooting c_trace rays (IGNORE_PASSABLE | IGNORE_PASSENTS | USE_BOX | IGNORE_ME | IGNORE_PUSH) through it from above (for example, in the green circle, below) result in the expected collision -- however, running it over other parts of the model (in the red circle, below) of it fail out as though the entity isn't present (i.e., the ray passes right through it):



3. Moving that map entity to another position sometimes fixes the problem.

4. I have been unable to reproduce this with a small test case, using the same models. I am using v7.73.1.

Question: Does this suggest anything? I'm trying to track down a way to either fix the issue or make it pop up in our test case, but with no luck.

Thank you!

Maybe, the bounding box, min_x/max_x etc. of the map entity is too small and convers only the green circle and not the red circle? At least, this is the best idea I have to offer .

Make also sure you compiled the map entity in A7 mode. Also, does it work without USE_BOX? If not, can you upload or send that level to Support? We'll look into it.

Thanks, guys. I'm going to look into your suggestions and try to get the thing breaking consistently so I can send something over.
