Collision problems

Rends · Post by **Rends** » Fri Sep 15, 2006 7:29 pm

Anyone else run into collision problems with invisible walls?

If i create a model than sometimes you can´t walk through doors/holes because of an invisble wall. this happen with or without collision models.
Not sure what cause this but i guess this happen more often if you use some XSI auto funtions like boolean (well i don´t bool anymore but i had this problem earlier) bevel , bridge polygon or resize objects.
so i either need to redo the collision model or break it in parts to fix this.
the docs doesn´t say anything about specific collision model forms like they do with terraincutter.

Yeah, I get this problem a lot (Library Balcony

). Still don't know why it does it, but I find I can fix it usually by toggling the vertex connectivity. That is, around the culprit area, split the vertexes so each polygon is a seperate piece. If it is already, merge them. It sounds wierd but I found this to work.

Maybe try triangulating the mesh.

I had a similar problem as I was also doing boolean functions in XSI.
Try making an option file with the following -donotmergecollision
or collisions (I am trying to remember from work) this allowed me to go
through openings that were previously blocked.

Rends, how about using a polymesh which you have full control of instead, then? Remember in SWBF1 when the solderi's collisions were only cylinders? Use the same and make a cube and boxmodel our of that. Then you'll hopefuly get a more 'clean' collision

and if I remember right you'll still have to name it 'collision'

Well qdin your idea will only work with simple objects or you would need to create a lot of cylinders/boxes.
