Will the SubtractAsync function receive an update? It breaks the lighting of the resulting union when used within a script. I initially reported the bug to the Bug Support Team back in December 2022, but it still hasn’t been fixed. I also reported it to the post, Studio Beta: CSG Has a New Engine - Vroom, Vroom, Vroom!, and it again still hasn’t been fixed.
Edit: As usual, issues with existing technology and suggestions are being disregarded.
@Shirovian Thank you for identifying this bug and for sharing the model with us. We want to inform you that we have successfully reproduced the issue and are currently working on resolving it.
This is incredibly amazing, because now I wouldn’t have to make door frames and windows using parts at an increment and/or have missing or combiner material textures on unioned parts. I am hoping that with the release of this update, we wouldn’t have the problem where unioned parts have an invisible hitbox where you can walk on.
correction on my previous post, sorry for the misconception
Since the last update the align dragged object feature was turned on so alot of builders may end up wondering why their objects will misalign and not slide across the boundary boxes walls which are always straight.
So if anyone is having the issue where the object is misaligned a lil bit its probably because this is turned on.
(Honestly, before it was really noticeable when an object auto aligned to a surface it jittered all over. but im actually surprised that this time it was barely noticeable that i couldn’t see it meaning that the the mesh right now is really good. Really exited to see how they interact with the physics engine )
Well, I wasn’t expecting to be shown just how out of the loop I am today, I never knew it was even possible to make unions in a running game, nevermind that it was multiple entire APIs ago. Yeesh. I don’t see much difference with the results (at least, in the examples given), though, and I haven’t actually made any in about as long either…
Pleasantly, that is. As a builder, I don’t think I’ve ever been this happy with a Roblox update. I just hopped on to build something after a bit of a hiatus, and I was jumped by the security vulnerability notification, so I got worried not all the issues had been fixed, but when I tried it… Wow.
Everything runs like butter. The separating and reunioning works flawlessly, it’s much faster, and everything is aligned correctly. The only thing I have to do is add smoothingangle.
This is incredible. I literally can’t put into words just how impressed and pleased I am with this update.
I seriously can’t thank everyone responsible for working on this update enough. Every piece of feedback I had was addressed and you all made good on your word to get it into a more than satisfactory state. I can’t imagine how hard the work to get this all working must have been, but it paid off tremendously.
Thank you all. Really. This is a game-changer for me, and I couldn’t be more happy with the results!
Are you guys able to provide any information related to the performance of CSG operations? (For example, what configurations of parts tend to be fast or slow, what combinations of part properties, etc.)
I’ve noticed that there is some variability in how long calls of UnionAsync() take, and haven’t tracked down the cause of that yet.
I am currently doing some work which involves a lot of unioning and would like to see what optimizations I can make (or at least what ways I can prioritise different operations so that I can get the bulk of the work done first and then leave the expensive things last).
Hey @EmeraldSlash ,
There should be a post coming out soon that goes into detail about both (hopefully exciting) new features for CSG and best practices on how to optimize performance
Will CSG be performant as meshes some day? It’s common knowledge that high use of unions or even moderate use is terrible for your game. I don’t really care to learn blender so I would hope CSG is my fallback.
Update:
As of September 18th 2023 (today), CSGv1 and CSGv2 are now sunset. The two Studio setting checkboxes that were available during the grace period are now no longer available.
Thank you to all those that reported issues during the grace period. We have addressed all reported issues in this forum post thread.
Please keep an eye out for a whole slew of new CSGv3 features and performance improvements that will be announced soon!
hello, idk what yall have touched, im having this big issue regarding this.
I want to union as i usually do, but after the latest update from 29/09/2023 i’ve been having some issues with Roblox. in the first place it didn’t want to open and started crashing some seconds away from finishing installing, so i had to go to any place from the website and press “edit” for it to finally open. it was the only way to get it to open, because it would be crashing when installing forever if i didn’t try that. After that, i tried to continue on solid modelling with Unions, Negative Parts & Intersections, BUT the unions started deforming and not showing how they have to.
A video of what i say:
I’ve also noticed in this update, the old CSG v2 Union settings in roblox aren’t available in the Rendering section of the settings anymore. Reproduction
Insert any of the given parts by roblox to start unionating
Union or Intersect two parts or doesn’t necessary have to be two, u can try with one, for example an sphere.
Watch it’s geometry deform anormally.
Expected (Bottom) vs Deformed (Top)
Here i can show you some examples i did.
I asked my friend about this and they don’t seem to be having this problem as for now.
I have tried Reinstalling studio , deleting all files , restarting computer , restarting Studio , checking settings , checking plugins , but nothing seemed to work. I suppose my friends haven’t got this “update” yet.
deformed unions.rbxm (192.3 KB)
Im aware that unioning vast amounts of pieces can deform them but these are the starter unions you usually use to start solid modelling. This feature has to work properly ASAP since is the main method i use for 3d modelling on my game.
Stopping me from developing.
you can notice the deformed geometry (left) and normal expected (right)
All the unions i wanna do get deformed ODDLY. i don’t know what to do ATP, no solution was found in the forum.
Hello @TimTsuki, the deformed geometry (left) in your screenshot is actually the LOD (Level of Detail) representation, not the original geometry. Please verify the Mesh Detail Level in the Rendering page of Studio settings. We were able to reproduce the issue after adjusting this setting to Level03.
Please reach out to us if switching the setting to DistanceBased does not resolve your problem.
Hello. Sometime in the spring, I made models and put them all in one place. Now I decided to get them out and work with them, but I found that I could not disassemble them. Any buttons in Solid Modeling do not work properly because of this, there are problems with loading models into the toolbox.
report_fire.rbxl (77.9 KB)
I just have over a hundred of these models and they all don’t work properly.
CSGv3 is giving me issues with cylinders, when they are turned into a union the geometry of the cylinders just get entirely messed up making them impossible to work with.
CSGv3 has more issues with errors than v2 did. I tried to edit one of my Unions made in v2 and the thing would not stop giving me error code -11 whenever I unioned pieces of them together (FYI, everything in this post isn’t just limited to editing old Unions, this even happens to Unions made in v3). I find the workaround to this is by moving the entire Union and its associated NegativeParts to a completely different position that does not line up with the original X, Y, or Z coordinate. Separating Unions sometimes results in the Union only separating a piece of itself but then leaving the original Union completely intact. I have to circumvent that using the same “move to different position” workaround. Sometimes it doesn’t even work and the Union continuously does the same behavior upon separation without spitting out any NegativeParts or other Unions (similar to one of my older posts Union is duplicating itself, and separating only a part of itself when separating. Potential bug?). Not to mention that I can’t turn off the NegativePart color inheritance on my Unions, and I have to color every NegativePart relative to what I’m cutting out, slowing down my workflow immensely. I feel as if CSGv2 was sunset too soon. While it may have had many errors, it was significantly less than the amount of errors I have in v3. I’ve halted five projects already due to my frustration with v3.
