scene: x-wing flying over mountains

[Bu3D]

There is another frame. I forguet to say that I´m working with particles too. in a little time i will be crazy because trying to see results when I change a parametrer this take me a lot of time :bounce:

If the vehicle isn't visible in the reflections I suggest you render out in layers, ie. you render the environment out to one set of images, then the vehicle in another set. Then finally you composite them together (which can be done with After Effects, Combustion, Digital Fusion, or even MAX's videopost).

This way you can concentrate on getting the environment right, then render that out once and for all. Then completly seperatly you render the vehicle, and you can tweak to perfection because you no longer have to worry about the environment.

If you need shadows cast from the vehicle to the environment, ie. cross-layer interaction, you should look up "matte/shadow" in the helpfile. Applying that material to the landscape will allow you to capture the shadows properly, but still without the extreme slowdown of the complete landscape.


I fear my description might be too vague to properly use if you're still getting used to MAX.. I don't know what I can do about that, it's too much to detail each step.. :shrug:


Of course, if you just want to speed up your testrenders you just hide the environment, you can unhide it later when you want everything rendered..

i will try to do this.

very thanks!!!!!! :bounce:

Also, for test renders, turn off anti-aliasing(huge performance increase), and turn off raytracing.

That will help alot.

Also, instead of turning of raytracing completly, you can also just turn off AA in the raytracer.

That helps a huge amount.

Also decrease the calculations for the depth of the raytrace. (I think the default is 9... drop it to 1 for your testing)

If the water is a flat plane with a bumpmap, then use the flat mirror map instead of raytrace.

Here's more tips on speeding up renders:

thanks!

i will try to changue this settings. the wather is a cube with noise effect animated with a raytrace material, and the particles effect is the think that do more slow the rendering.

another question, if i want to model one character, what's the best number of polygons (a limit of polygons)? for exemple: a leg´s character, what is the suggestly number of polygons?

thanks to all!! :bounce: :scream: :drool:

That last question has been answered many, many times. Please search the forums for the answer.

Also, in the future, you should ask seperate questions in a new thread.

Particles are quite fast most of the time, unless you use massive amounts of them.
I think it is much more likely that the raytrace maps are slowing your render down. Use a plane with a flat mirror instead: better results (nicer antialiassing) and faster rendering.

Shadows is the second thing to slow the rendering down, especially raytraced shadows.

As for your question about the character polycount, the lower the better ofcourse. But since you are not making stuff for realtime the polycount doesn't matter that much, as long as your machine can handle it.
