Tepe Posted February 24, 2017 Share Posted February 24, 2017 Hi, im new in this forum, and i will introduce myself exposing my problem with poly bridge. I used the Polybridge node to connect the external part of the rim with the central piece, but when i subdivide the mesh, i get bad topology and no smooth on the red edges as shown in the images. I will appreciate any tips to fix this problem. thank you and sorry for my english Quote Link to comment Share on other sites More sharing options...
f1480187 Posted February 24, 2017 Share Posted February 24, 2017 (edited) Turn off backfaces when model: D > Optimization > Culling > Remove Backfaces. If it is an orientation issue (tube is reversed, probably), use Reverse node. Edited February 24, 2017 by f1480187 Quote Link to comment Share on other sites More sharing options...
nisachar Posted February 25, 2017 Share Posted February 25, 2017 Unclear what you mean by bad Topology. From your screenshots the topology seems to behave as expected. Quote Link to comment Share on other sites More sharing options...
Tepe Posted February 25, 2017 Author Share Posted February 25, 2017 thank you for your answer, but i still couldn't fix the problem. the subdivide don't affect the red edges area :(. @nisachar i have a bad topology flow where the rays connect to the rim, the screen don't show very well this issue, my bad, but i fixed it increasing the division of the rim.

Iraklo Posted February 27, 2017 Share Posted February 27, 2017 I think you need to consolidate points. Try adding fuse node after bridge. Quote Link to comment Share on other sites More sharing options...
nisachar Posted February 27, 2017 Share Posted February 27, 2017 (edited) @TepeYou might be onto something here. I have posted a similar issue on the side fx website. Hopefully, someone will have a solution.

nisachar Posted February 28, 2017 Share Posted February 28, 2017 (edited) The subdivide node seems to throw up some bug and doesn't evaluate the edges properly where the polybridge joins the two ends. It treats them as 'unfused' The workaround as of now seems to be to add a 'çlean' before adding the subdivide node. OR maybe add a fuse node after the subdivide Thanks to friedasparagus over the sidefx forum. Edit : It might be due to the fact that the normals for both primitive sets are in the same direction. Add a reverse sop to either one fo them before the bridge. Edited March 1, 2017 by nisachar solution Quote Link to comment Share on other sites More sharing options...
