Flacracker Posted March 29, 2009 Share Posted March 29, 2009 I am getting some horrible performance with 3DS Max 2009. I think it is kind of dumb too... I can play Crysis on Very High and no AA at 15 FPS. But really... I can play Fallout 3 on mixed settings between High and Ultra. And when I go into my gun model on 3DS Max it is lagging like crazy. My simple model takes up so much Memory its not even funny. I don't even have it textured or do I have smooth on. Do you think the Booleans are making it slow down a lot? I'm going to get some more memory soon but it really makes no sense that my model is using up so much memory. Is there any way to increase performance in 3DS Max? because it is just eating up so much at a time. I looked on the task manager and it was using 1 million k. So what do I do?

Flacracker Posted March 29, 2009 Author Share Posted March 29, 2009 I am also modeling this: http://img7.imageshack.us/img7/7885/penetratormodel.jpg after this: http://img11.imageshack.us/img11/2443/penetrator.jpg And no... I am not done. Link to comment Share on other sites More sharing options...

TGBlank Posted March 29, 2009 Share Posted March 29, 2009 3dmax performance problem -> ask in 3dmax forums maybe?This is hardly the place to find that answer ^^' Link to comment Share on other sites More sharing options...
necKros Posted March 29, 2009 Share Posted March 29, 2009 Dunno. Is the cpu lagging, or you are running short of memory? In the first case, check if you have hardware acceleration enabled in 3ds. If it's the memory... well, try to collapse modifiers that you don't need to change anymore, if you have them. I don't have many experience with 3ds, so it could be anything else. Maybe it would be wise to ask in the autodesk forums as TGBlank suggested. Link to comment Share on other sites More sharing options...
Treebiter Posted April 5, 2009 Share Posted April 5, 2009 Silly question but how many polys is that gun in total? You say you're not using smoothing but there are some very smooth looking sections that lead me to believe it's pretty poly-intensive. I have a Crysis-killing rig but it can crawl with very high poly meshes in max. Also, I'd recommend against using boolean operations for use in a game model. It's just as easy to patch-edit the desired shape into an object, though it can require a bit of planning. One last thing, is back-facing turned off? Other than that, not sure.

Yeah I just got some more memory for my computer and I restarted my model... But I think i was getting some bad preformance was because I was subtracting using shapes that had like 47 segments each way. Link to comment Share on other sites More sharing options...
Deleted1084753User Posted April 5, 2009 Share Posted April 5, 2009 Uwaa? Using boolean subtracts? BAD idea, seriously, they're messy as hell and don't play nice with games (as Treebiter also mentions). Stick to Edit Mesh/Poly/Patch. Edit Poly would be preferred since Max 2009 has some impressive speed boosts in edit poly mode over earlier versions. Link to comment Share on other sites More sharing options...
Treebiter Posted April 5, 2009 Share Posted April 5, 2009 Think we've hit the nail on the head. It's not unusual to think of a better way of doing things mid-model and restarting, and to be honest, it usually works out better for it. One last thing I'd recommend is keeping an eye on the poly count. The Game model doesn't need very smooth curves as you can cheat to some extent with smoothing groups. Also, you can make a high-poly model and capture the detail as a normal map and then apply that to a your low-poly model for even greater peformance gains. Here's a good run-through... Just in case you weren't aware :) http://www.bencloward.com/tutorials_normal_maps1.shtml Link to comment Share on other sites More sharing options...
