I've just downloaded it and I'm loving the feature set this has. Being able to do variable heartline and friction is an absolute godsend for some of the weird stuff I like working on.
I've noticed what I think is a bug when using curves and geometric sections together. When you place a geometric section after a curve the pitch and yaw carry over from the roll, even when using lead out. So for instance trying to create a lift hill with a upward curve followed by a straight geometric section results in a curve followed by an incredibly tight geometric spiral ( more than 50 rad/s usually ).
If there's anything I'm doing wrong with how I'm configuring my nodes, I wouldn't be surprised, so it might just be on my end. I'm running the mac version on an M1 too, so it could be Apple being Apple
I’m glad you like it!
The pitch/yaw speed getting carried over is intentional, since it allows you to transition very smoothly between force and geometric sections. However, it does feel unintuitive after curve sections. Maybe I can zero out the pitch/yaw speed after curve sections.
In the meantime, you can just keyframe pitch and yaw speed to 0 at the start of the geometric section
I just downloaded for Mac OS and it says that the file is broken and can't be opened. I am on Sonoma.
Any help would be greatly appreciated!
No problem! You can fix this by running
xattr -d com.apple.quarantine /path/to/KexEdit.app
replacing /path/to/KexEdit.app with your local path, then run the app.
This will be fixed when I pay $100 to apple so I can security sign the app myself
I tried running this prompt in terminal and was told "No such file"
If I have it in my applications folder would this be correct?
xattr -d com.apple.quarantine /MacintoshHD/Applications/KexEdit.app
Is this correct?
I'm now being told "Not enough arguments for option -d. Expected at least 2 but got 1"
I think the path you entered may be incorrect. It might be something like “/Applications/KexEdit.app”.
I believe you should be able to write
xattr -d com.apple.quarantineand then drag and drop the file from the finder into the terminal to automatically write the correct pathThanks! I should have come back to post that I got it working with the help of ChatGPT. I probably butchered the copying and pasting somewhere along the lines and I'm no good with Terminal.
