Error adding emitter: AttributeError: 'RigidBodyWorld' object has no attribute 'steps_per_second'

Domoninic opened this issue 4 years ago · comments

Using Blender 2.91.0 I have installed the addon but every time I create a new emitter I get this error.
The addon seems to work except that the path is not projected.

OS details:
Edition Windows 10 Pro
Version 20H2
OS build 19042.685
Experience Windows Feature Experience Pack 120.2212.551.0

This is the console log from starting Blender and, with the default cube selected, creating a new emitter:

Hi @fatoms, I have a fix for this and should have a new version released in the next couple of days. Thanks for the reminder!

Hi @natecraddock, I just tried the updated master branch, the error is gone and Trajectory projection is working expected. Thanks.

You're welcome! Closing now that I have updated to the 2.91 API changes

Hey same error still occur on blender version 2.93.1

@MohitDevli I just downloaded the most recent version of Projectile and installed it fresh in Blender 2.93.1. I do not see any issues. Do you have the most recent version of Projectile?
