I started having problems loading the LAMH presets when I went to 4.8. But even in 4.7 it was crashing as soon as I hit the render button.
Do you mind my asking what kind of RAM you have loaded into your system? As in how much?
LAMH fur is Fibermesh. Fibermesg can be very, very heavy on a computer's resources. It crashed out my old system if I tried to load it as well, but my new system has a lot more RAM, and I so far have not had that kind of a crash issue with it on 4.8.
It should be noted - LAMH does not like it if you back out of the operation. If you click th button to load an LAMH preset, you have to load a preset. Hitting cancel will make DS crash to the desktop straight away.
Also - are you using the full version of LAMH, or just using the free player to load the presets?
I also find that adding a fur preset is the last thing you should do before the final render. Set up your scene, then save the scene one more time. THEN load the fur preset, and click render. Do NOT save a scene with LAMH furs loaded, as these can frequently corrupt the scene's save file, and are very tedious to edit out of the scene data.
I don't know if any of this helps - these are just my own observations. It also should be noted - some folks just get nothing but constant crashes with it, while others get constant crash issues with Garibaldi.
I can't use Garibaldi, but LAMH works like a charm. Others have the opposite situation...
