Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[Request] Meshpainting Large Object Warning

When you meshpaint a massive object and use the "Fill" tool, it will try and create a large number of meshes and will freeze up or crash. If it gave a warning that you are going to add a ton of objects and allow you to cancel the operation that could save time if you were to accidentally click the wrong thing.

Hi Alex,

I was attempting to reproduce this for the report, but I am having some difficulty. By "massive object" do you mean extremely high poly or very far scaled up? Do you have a callstack for the crash? Also, what are your computer hardware specs? These will all help greatly in getting this issue resolved.

Thank you,

Alexander

Let me try and re-create the issue. The mesh I was using was fairly high poly (to paint onto things), but I could paint many instances, and no issues. It's the fill tool that causes issues.

If you use the fill tool, turn your paint density up, and then paint say, your skybox, the program will lock up. I understand it's trying to make a lot of objects It's not so much a problem that it locks up, but rather if there were a warning before you end up filling a mesh like that, and pretty much making the editor unusable would be nice. It's like how when you are about to subdivide a mesh a lot in maya, and it says "hey this is possibly going freeze and or crash the program, do you want to continue?"

I have x2 Sandy Bridge 2650 8 core processors 64 gigs of ram and the worst part (seriously) sli Quadro 4000's.

Same thing on the other computer I tested it on:

3930k @ 4.2 Ghz 24 gigs ram 780 GTX

Thanks

Thank you for that. I set up a scene for testing, but I am not seeing a "paint density" property. What exactly are you doing to turn that up? Thank you.

My apologies.

Alright, I am seeing the lag now. I need to test this further. You said there was a crash? Can you give me the callstack for it?

I have never let it hang long enough to get a real crash but it hangs for a good 20 minutes before I exit. It would just be nice if it warned you before you slow it all down, and make the program unresponsive.

Alright, I have update the report with this information. Thank you very much.
