Hello,

excuse me for the time I took to answer.

One issue that has been addressed in the past is the move to 64-bits.
I will again try to answer it precisely.
There are many recent clothes or hair that generate memory errors.
To solve this problem there is a solution... the passage in 64 bits which solves all the problems.
Unfortunately it's not that simple.
The meshes that generate these problems are either:
   - unnecessarily fine meshing
   - meshing having meshes with very different sizes.
These two types of meshing are not suitable for numerical simulation.
For me, the best solution is to correct these meshes to make them compatible.
Going to 64 bits would mean being able to simulate 100 million springs or more. This will be slow and probably unrealistic.

Prior to my eye problem, I had made many modifications to the program.
These modifications make it possible to create garments with a regular mesh size and an adjustable and precise UVMAP.
I also worked on generic clothing for Victoria 8 allowing to create almost all types of complex clothing.

At the level of the hair, I integrated into the program a method of generating hair based on extruded triangles allowing to obtain much more realistic simulations than the meshed bands because of their structure which makes it possible to easily control the rigidity of the locks of hair and especially to tie the locks together which makes the rendering much more realistic.
This hair can be subdivided using a powerful smoothing method in the case of static rendering.

All these functions work perfectly although there will certainly be improvements to be made.

This is where the current development of the program is.
Now my problem is whether my choices are compatible with your wishes.
If your wishes are to buy a piece of clothing or a hair and have a perfect simulation at the press of a button, I might as well stop right now. because I would have the impression of playing "Don Quixote" and fighting against windmills. I could never give you what you want.
If you want to obtain very good simulations by accepting to spend a little more time in order to obtain the best conditions which will allow a quality simulation, then I am ready to work with you.
I am also ready to work on a mesh correction program although this work is one of the hardest there is.

I know, and I've already said that the most important thing will be to make videos clearly explaining everything I'm trying to express now.
The association with Dan will find its best justification there because of a good distribution of tasks and my disastrous English.

Please give me your opinion!

Dan, I'll send you a long message tomorrow.
If you don't see it, tell me here after tomorrow.

anupaum, thank you for your image.

Friendly to all.
