View Full Version : Help With Reducing Polygons of Large Model

Being a newbie at LW Im struggling with a large model render time.
Ive tried using the Reduce Polygons + function but oddly it seems to be doubling the polygons not reducing
them. Also tried the Reduce Polygons that wrecks the geometry.

Any tips or help in getting the model shrunk down would be greatly appreciated!
Happy to share it with anyone who might be able to reduce it.

Thanks,

Carl

Back in the day large models with lots of polys did effect render times - today not so much. I suspect something else is going on. More info needed. :)

True. I was able to cut the render time in half by adjusting some things in Render Properties.
Still, the polygon count is at least 5 times what it needs to be.

Thanks,

Carl

THere are a few paid plug-ins that could help a lot (remodeler at Hurleyworks, or easy mesh simplifier as part of OD_tools if you are on LW2018). These two plug-ins rely on an application which is also available for free, and is called instant mesh. Export your file as .OBJ, perform the automatic retopo, import back. Not perfect and if you have UVs they will be destroyed in the process, but if your model doesn't have to be animated, certainly the more efficient.

can you show a picture of your object?!
normaly REDUCE POLYS + works fine

.. but you also can try it with the extern freeware MeshMixer (via OBJ import/export):

Not sure...thought this came up in another threadl..if it was you or not? and if you were on mac its a no no.

otherwise plg simplify mesh does a good job, its within the plg uv tools package and its free...

Does a great job on extremely dense photogrammetry meshes from sketchfab, while maintaing uv maps.

ckeyes888, what version of LW are you using? Depending on the answer, there may be better solutions for more directed control of the polygon reduction.

I do highly recommend Hurley's Remodeler for LW (http://hurleyworks.com/portfolio-items/remodeler/), if you're looking for a commercial solution. If you can find it, QEMLOSS3 also works pretty well for percentage-based and other parametric reductions, though it may not work in LW2018.

Thanks a bunch all. Turns out the real culprit was in the Global Illumination setting for Rays.
Was set at 48. Set it to 2 and the render time dropped by 80%. Can’t really see any difference in this particular render.

PLG_Simplify is not the faster reduction plugin in the world but faster than every other free tool for Lightwave, with Vmaps protections (UVs, Morph, Weights...)

Does that work with Lightwave 2018?

Yep. :)

Yep. :)

Thanks! I've only kept it in v.2015.3 because it hasn't been updated in years! I wasn't sure it would still work!
