In 2.9 decimate modifier lost its factor slider. I personally was using it for retopology, specifically to control
the proportion of topology’s dencity. Its not really vital for retopo, but it helped, especially when the result of its work is not visible in weight paint mode, and you can’t monitor the decimated topology in real time as you edit it through the weight paint.
The new modifier panel is great, but its sad to see occasional functionality losses, like it was with height map baking, instead you have to go with workarounds with camera, and depth channel, which is a setback.
- Suggestion for bevel modifier, when first applied it should have its default limit method set for angle not for none. Otherwise it creates perfomance issues when applied to a high dencity model.
