Question qemLOSS2 Problems

for some reason it wont work?

i have a model thats 83680 polygons
i click the layer its on (with a blank layer beside it of course) then i click qemLOSS2 and enter a number like 600 in the goal in polygons and i set perserve mesh quality because i want to keep it the same and i leave all other settings at default.

i press enter and it processes for a few seconds then it creates the new layer as if it worked but the new layer is just a copy of the first one. with the same 83680 polygons?

why isn't it actually working?
it never has on any model?

i want to practice normal mapping but if i cant reduce polygons its kind of pointless. i downloaded the normal maps tutorial video off this site but he didn't explain how he used qemLOSS2 so im confused.
please help. thx!

Hmm. Possibly because the number of polygons is far too low for the plugin to calculate. 600 polys from an 80,000 poly mesh is incredibly optimistic - especially if you're trying to preserver the mesh quality. Try reading the Lightwave manual to find out how the tool actually works since there's a lot of parameters in this one, and maybe try reducing polygons using decimals (aim for around 70% - hint: that's 0.7 in the Goal field).

IMHO, you get better results if you make the low poly model yourself.

remake the entire model?
the reason im making it with high poly's is cuz im using the normalmaps shader to put the high detail on a low poly model.
if i were to remake it low poly the odds of getting the shape exact again is nearly impossible.

i emailed the author of the qemLOSS3 to try and get a copy but i've gotten no responce, im really having trouble with this, i made up a fast head to show what i mean. if you can watch the video to see exactly what im talking about maybe it will help?

thx.

Take a look at the image I attatched below.

You'll see that I started with a subpatched object that I froze later for my high poly object.

Next I tried running the high poly object through QemLoss to create a low poly object.

I didn't think the results were very clean so I made a new object with the high poly object in the background. The end result is the low poly object in the picture.

The truth is no matter what you do your low poly object is not going to match the shape of the high poly object. The trick is to construct a low poly object that projects a similar shadow but retains a smooth topology. The details on the object itself will be handled by the normalmap.

As for why QemLOSS isn't working for you at all, I'm not sure.

I think the plugin needs removed and reinstalled. Something is quirky.
