shotzz5 commented 3 years ago

ive tried unisntaling and instaling the addon tweaked about with everything but for some reason they just dont generate

friggog commented 3 years ago

What version of blender are you on? Also by not generating do you mean it crashes or nothing appears or an empty mesh appears?

shotzz5 commented 2 years ago

sry for the late response, im on blender 2.93.5, by not generating them i mean nothing leaf related appears, just a trunk (is i triple checked i have leaf gen on)

Well, the good news is that Treegen is running, the bad news is that something is causing an error. There will be an error in the Blender console (Window > Console), would you mind taking a screenshot of it?

Just tried on 2.93.5 and everything works for me, would be great to have more info (type of tree, traceback as Luke suggested etc)

Just happened to me. Not entirely sure how to repro, since the problem only really happened to me after I've been spending a lot of time in one scene generating hundreds of trees as I tweaked the parameters. Luckily, I've got the error log and it's an easy fix. I've made a pull request #70 with the fix, but for posterity here's the error log the fix is based on:

Closed by #70 - thanks @ThisIsADogHello for the quick fix after repro!
