Hi, I loved your addon, I have a request, could you add erosion for arbitrary gravity according to a lowpoly surface, what I mean with that we would have a lowpoly model, with an option you should change particle gravity direction according to lowpoly face normal where particle at, I wanted make a planet but erosion can only happen in Z direction, and that messed up my sphere, otherwise addon works pretty well and thank you
After installing v1.0.1 and v1.1.0 Hydra at 4.3.0a, 4.2.0, 4.1.0, 4.0.2 and 3.6.2lts blender versions with installing moderngl from extension settings and manually after-installing moderngl-5.10.0 with console, every time trying use it like press any button related to settings panel, i receiving something that:
Python: Traceback (most recent call last):
File "/home/archy/.config/blender/4.3/scripts/addons/Hydra/addon/ops_common.py", line 64, in invoke
erosion_particle.erode(target)

vao = model.create_vao(ctx, data.programs["heightmap"], vertices=verts, indices=inds)
~~~~~~~~~~~~~^^^^^^^^^^^^^
KeyError: 'heightmap'
At first i tried install moderngl from extension settings panel, and it said that installing was successful and blender need to be restarted, but after restarting, hydra noting that moderngl not installed, I checked through the terminal whether the module was installed, and yes, it was installed at /ver_blender/python/lib/python3.11(or pyton3.10)/site-packages/ had 3 directory related to moderngl, btw in blender has appear Hydra panel but result above, i tried reinstall moderngl manually with
./python3.11(3.10) -m pip uninstall moderngl in directory with bin python but without result
I tried many version as wrote to be sure, cause previously (several month ago) i used 1.0.1 at some 4.* version blender, and i remember that had some issue and i fixed them with manually install moderngl, but this time i cant fix that
My system is linux arch and i dont know what i doing(
Hello Bro, thank you for sharing this amazing tool. It is working with blender 3.6 perfectly. But blender 4 is not. It give an error like "no attribute hydra".
I am sharing it in blender artists. I hope you don't mind.
Is there any chance to convert it to nodes?
And good luck with the thesis.
Hi bro, nice to see you are updating this amazing addon. Just a suggestion. can we convert this addon to a node based one?
