I also noticed that the minimum scaling for unions has gotten larger, as before, I had unions as thin as 0.005, now that has gotten bigger and the signs are now overlapping and are z-fighting as shown.
Yes, someone else reported this too and I’m looking into it. Seeing as some people were using letterbox scaling to “cheat” the minimum size, this would be a good time to modify that limit and it looks like it’s mostly a legacy leftover that we can remove.
Really neat! I use this to “flatten” the normals on a part before performing operations on it so that decals get project on the faces that I want them to. I then resize the part back afterwards.
Here’s a spray paint tool that I was working on.
Before (when used on sharp angles, the texture only gets projected on one of the sides):
Can use this for resizing ball parts instead of a ball mesh, heck, why stop there! Create yourself a hole collection of custom non uniform resizable parts!
Hell yeah! I haven’t used Roblox Studio in ages, and I’m really glad to see this feature. I’ve been waiting for it for as long as CSG’s existed.
I wish the UVs could be rescaled (or whatever’s causing this issue) like MeshParts, however. Though I’m sure something like that is coming in the future… right?
Just an update on this feature: We did decide to go with a three-phase rollout for this.
Some time next month the Beta will be disabled and the functionality will be available in Studio and on production by enabling a three-phase rollout flag called “UnionsScaleNonuniformly” under your Workspace.
There will be a fresh announcement post with the planned schedule when the three-phase rollout becomes available.
You can correct this by unioning a disjoint negative part to the union to adjust the bounding box orientation without changing the geometry. Note: What order you select the parts in before unioning determines which one’s orientation is used for the union.
Textures should tile correctly even on very nonuniformly scaled CSGs, no more stretching.
CSGs can now be scaled down to 0.001 studs on any axis. Removing the limitation to 0.05 studs was missed when doing the minimum part size changes because of the slightly different pipeline that CSGs use. This will introduce additional backwards compatibility concerns, where some CSGs that were scaled down as thin as possible may now appear thinner than intended.
Is this for newly created Unions or ones you created before I shipped the fix? The UV metadata is generated at the time you created the Union, so you’ll have to separate and reform any unions you created while it was broken to get the correct UV metadata which avoids stretching.
