Change brightness/contrast/saturation of textures: How in SR1?

[kwistenbiebel1]

The title says it.
when I change one of these characteristiques to a sketchup material, it does not change the texture appearance in the rendered output.
In the Vray material editor there are no options to set these things.

So my question is. How can we change these things without having to go through photoshop for each and every tiny change (e.g texture brightness) we want to make to textures?

Thanks in advance for your answer,

If you could find an example of how this is done in another 3D modeling application, that would be helpful. We are beginning to lay out plans for our next release, so now's the time to send us feature requests.

the simplest way to do this is to go into the map through the v-ray material editor. You'll notice on the left side there's the multiplier. Just increase that a little for a brighter map and decrease it for a darker map. Its not exactly the same, but its quick and usually gets the job done

Thank you both for your answers.

@Dkendig,
Both Fry as Maxwell have the option to make changes to the textures in the engines mat editor. The Fry one is pretty extended. (gamma, brightness,contrast,saturation, hue,clip white/black etc...).

In the first release of vray, I always rendered a test without any linking of materials or setting up vraymtls so I could change the colors of the textures in the SU material editor.
When the colors were fine, I started making linked materials and they inherited the color changes of the SU textures.

In SR1, all the SU materials are linked at start up of the SU model (which is great by the way! ), but you can't change the texture attributes anymore after that.

That is why I posed the question.

@Dalomar,
I already use the multiplier on textures to brighten textures up/dwn , but it is kind of limited.



Oh yeah, and another thing:
It seems that the output of SR1 looks somewhat paler than the original Vray version.
Were there changes in the gamma settings or linear workflow?
I am testing it on an exterior file, and my conclusion is that the output misses a bit of vibrance, even when using a exponential tonemapping D 3.6 and B 3.6.

Biebel

There were some small changes to the Physical Camera...that may be what's causing things to be slightly paler

RC1 - Also, I found that emmissive materials in old scenes need to be drastically turned down, as they burnt out the scene. Typically something I had set at 50000 (a background with the sun and physcal camera) had to be re-set to about 10 in RC1.
(Nobody has mentioned vray lights yet - check them out - a whole new ballgame!!)

the fixes list mensioned that the physical light units were corrected so that physical camera and default camera were more similar in handling lights...
