Speed vs Quality (Maximizing Polygon in 3D Max)

In here, i would like to show some helpful modifiers that will maximize the use of polygons to
our models. But before I go so far, have take a look first on the idea on which factor our project
must consider, is it the quality or the speed. Of course both must consider, decent renders at an
appropriate time. But sometimes these two dont works at the same time, so these tips might come handy.

So basically, one factor affecting our rendertime are the number of polys, and here are some methods on
how to reduce them without sacrificing the quality.

A. MULTIRES - The MultiRes modifier reduces the memory overhead needed to render models
by decreasing the number of vertices and polygons. This is useful not only within 3ds Max Design
but for content creators who export models for use outside of the program, such as in Web-based
3D applications.

So here is our sample, form evermotion archmodels, the number of polys and vertices can be seen
on its active viewport ( just press 7 on your keyboard to show it)



1. Select your model, go to modifier list and select MultiRes.
2. After selection, hit Generate to activate and process the modifier






3. Under Resolution, you will see now the tabulation of polygons and vertices. Now under Vertices,
make it 75 instead of 100 then hit generate. The polys and vertices are dramatically reduced.and here is the comparison



And the rendered image comparison....so far a bit was change but not noticeble. And if you will just use this
model 5 meters away from the viewer, you cant determine that it was modified



4. How about making it 50. Almost half of the total polys will be deducted. Here is the comparison of thier tabulated polys



5. And here is the rendered image comparison. As long as the rendered image is acceptable,
you are free to lessen its vertices count



6. Okay, how about making it in 25 percent, still the artifacts is not noticeable



Just imagine the scenario, if this model was copied ten times, you can save a lot of polys

7. And if, say you want to preserve a certain parts of the models as it is, or i mean you want to preserve the details.
Bring back the original mesh at 100 percent, hit generate. Then go to sub-level of the MultiRes Modifier, select vertices.
On the model, select the areas you want to preserve its details ( window selection) then go to MultiRes Parameters.
Under generation Parameters, tick to activate Maintain Base Vertices, then hit generate......



It will convert the whole mesh except the area you selected.

So thats it for now and let us go to the other modifier.
Next is Optimized Modifier.....for continuation

nice one sir. very helpful

Mabuhay ka!

-WOW! very nice sir! thanks a lot for sharing!!!

sir onel maraming salamat very helpful talaga ito

isa na naman kaalaman mula sa ating walang kaparis na master onel...maraming salamat po!!!!

thanks for sharing master...i learned a lot...mabuhay ka!

galing nito. malaking tulong ito master! thanks for sharing!

ganun pala yun..ang galing nito salamat sir

Ok to sir! thanks for sharing! master talaga!

salamat master

The problem with procedural polygon reduction tools is that they do not care about the UV mapping. The higher the value you use, the higher the probabbilities that it will have a negative effect on how your objects are mapped. They ultimately destroy the UVs because they are dependant on the vertices.

Of course this is fine if the materials do not require UV Mapping like that of the above example.

One way to get over this limitation is to learn how to use Normal maps, Retopologize or model them yourself.

If yo uhave multitudes of the same object, either you instance them or if you are a vray user - just use proxies.

galing..... salamat master....

I agree with v_wrangler's remarks and suggestions.

In my experience ProOptimizer works a lot better than MultiRes, minus the selection feature (although you'd probably be writing about this later). Of course rendering involves more than just the number of polygons. Your image sampling settings are actually more crucial. So as the quality of GI and shadow you choose to use. The biggest problem hi-poly scenes can cause is 'running out of memory'. For which the solution is better memory management and more RAM of course.

As for keeping details while maintaining speed in a heavy/dense scene, Vray proxies are the way to go. This is all assuming that memory is not an issue....

ayos to. dagdag kaalaman n nmn. sakto sa gngwa ko ngayon. thanks a lot for sharing!

thank you sir for sharing. the team appreciate it so much. god bless sir...
