hey like iv said on various boards im relatively new to lightwave. Is there any tips for when im rendering that could help enhance my models and textures ?
all feedback is appreciated

Go find the Radiosity option! (Render globals-->Global illumination-->turn on Radiosity.)

Give your scene a background color/image (ctrl-F5-->Backdrop)

Put in some lights as you wish and render.

Tweak some of the settings to see what they do :)


Radiosity takes a long time to render but the results are very nice!

Turn on 'Interpolated' too, it'll go much much faster.

here's some more
decent and really fast anti-aliasing : use the perspective camera (camera properties), antialiasing 1, gaussian reconstruction filter, adaptive sampling on, 0.1.

render speed with raytracing: reduce the Ray Recursion Limit (render options, render tab) from 16 to 4. (overlapping transparency or refraction may require more)

keep in mind to make as real surfaces as they are in the real world. There is a "Genereal balance rule" You should follow:

Diffuse + Reflection + Translucency < 100% ("less than" not "less or equal than") but when u get to dark materials U can set the light source to even 1000% - that will still be real.

Never use Specularity - set it to 0 and forget about it. Use only reflection

Remember that the world we see depends mostly on the light, so pay attention to this first, than set the surfaces. I usualy keep the Diffuse level on 50 - 60% for bright and low reflective surfaces, and 10 - 20% for dark or very reflective surfaces.

Hope that will help,
Cheers!

Specular is ok, if you're careful to make it look realistic. Since cg lights can't be reflected in LW, it has it's uses.

Hmmm, 50-60 diffuse seems fairly low. How do you keep your scenes from being dim and dimmer? How many lights do you tend to use and how bright are they for say a typical indoor day scene?

He's talking about surfaces that have more than just diffuse, and he's right. You don't want 100% diffuse on something that also has 50% reflectivity. The total reflected light shouldn't exceed 100%, as a rule of thumb.
