(Solved) In-game lowpoly, tris on cap make sense?

bitinn

Hi,

Besides Sub-D requirement, is there any benefit to using more quads on a cap? For example:

The model is intended to be used in-game (on less than powerful hardware).

No. If you want to make it it slightly more optimized - reroute edges to make them all horizontal or vertical - you will save 2 tris. As far as I know it's even better for overall performance, but I'm not sure.
Still,there is a case, when this additional geometry can be used - if you have one smoothing group - you will decrease the amount of gradients, but that a rare case.

Good point.

Somehow I missed it. Horizontal/vertical slices are the way to go then.

Well, at less 1 drawback of all slices on cap: bevel would be limited due to the thin quads.

Add more cuts perpendicular would help, but effectively move it closer to other quad-based solutions.
