HOW TO MAKE A MATERIAL FIT TO OBJECT?

good day.

panu po ba e-fit to object yung material? example, a picture na e-aaply sa picture frame..

thanks in advance..

at dagdag na rin... ang pagcreate po ba ng pure white na texture. ay ang diffuse ay gawing white lang? walang ibang kung anu pa man. para sana maging pure white..?

answers to your questions;

1. put uvw mapping modifier on your object, under modify tab, select bitmap fit
2. use vray cam instead, under custom balance drag down the slider to pure white.

thats all and goodluck

There are many factors involved in maintaining an RGB255,255,255 (white) value in your renders. First and foremost the color of your object will be dependent on the lighting setup, your lights will contribute to its total illumination, GI as well will contribute to its global tint, it's placement in the scene is another factor as well (is it under a shade or is it under the cones of your light sources?)

If you have a white diffuse color - it will be obviously whiter if exposed under direct lights, that's why it is important to CLAMP your colors so that they will remain white even when there are other factors that may contibute to it being more white (float) than it should.

Another way is to lower the values of the diffuse colors (245,245,245 for example), making them a bit darker and adjust as you make test renders. The same thing goes for perfect reds, or blues or greens or yellows.

Custom Color Balances under the vray camera might help but it won't help clamp the colors to a maximum brightness unless clamp is on under color mapping.

Consider white balances as a global tint. It doesn't really make your whites white - it simply controls the saturation of the colors based on the color you put in the custom white balance slot.

My advice if you want to make sure white is white under any lighting condition, is to make test renders as you adjust the diffuse color (making it a bit darker) and controlling the colors and intensities of the light sources, GI environment color and intensities as well as the reflection levels.

many thanks sir wrangler, im also enlightened!!!

sir. maraming salamat po sa advice.....

To aid in comparing your test renders, you can use the hidden history feature of the vray vfb

sir salamat po sa link... first time ko gumamit ng vray nung wensday.. at gamit ko 3dsmax9 vray adv.1.5 rc3
applicable po ba eto sa version nang sa kin?

at sir tanung ko po. ano po ba yung tamang material setup sa medyo transparent na curtain?

kasi yung ginawa ko diffuse white at refraction medyo pinaputi ko... at parang yung curtain ko masyadong maliwanag...





(is it under a shade or is it under the cones of your light sources?)
sir v_wrangler, eto rin po yung white na sinasabi ko yung door po na nasa right side..

Really neat!
Thanks for sharing sir vertex

maraming salamat master v...
laking tulong po nito..

The reason why the curtains look too bright is because you have a very refractive surface and then it refractsa the brightly lit white background behind it. Also it helps to add a bit of glossiness to your curtains so that the sharpness of the bg is at least minimized.

As for the door on the right side - you might try checking the camera for white balances make sure it does not point to a color other than white. Adjust its diffuse color, btw, remember that if you have lightsources pointing at the door and they have color - any object even in real life will pick the same - isn't that what's happening here?

Another trick to make sure your surfaces reflect their own color (diffuse) is by adding a bit of self-illumination by doing so - the effects of surrounding lights specially shadows which can tint them - are minimized.

As I mentioned in the past, the trick to getting correct lighting or White Balances is to make sure you test the lighting scheme using all white objects first.

White room,white walls. Put a white object, a teapot perhaps and make test renders. If you are able to make a technically-white(RGB 255) textured object look really white in the renders, then anything other object you put in there afterwards will surely get their right white balances without extra effort.

salamat po sir sa mga advice.
