Opacity control for every kind of material

[solodesign]

Nowadays is possible to enlight so many different kind of surfaces so it is needed the possibility of giving transparency to every kind of material, may it be stone or concrete, too.
Other render softwares already provide this option.

You can do this by applying an opacity map to the material.

I do not agree with this.
An opacity map does not regulate the opacity amount you need to give to the material.
An opacity map can give transparency in particular points.
What I mean is a simple cursor command like the ones used for scaling textures which increases or decreases transparency.

I know what you mean. In the meantime you can control the amount of transparency with an opacity map using an image that is x percent gray. Try it.

That's what I do .. I've got a set of 10px by 10px gray scale images ... not very handy, but it works indeed.  A simple slider with the option "even opacity" would be nice and would make fine-tuning much more user-friendly .. which is, what KS is all about, no ?

So for the future of KS .. I put my +1 right here

It is on the list of things to do.

In my volume rendering days (VoxelView and Vitrea) we only had two controls, color and opacity and they were assigned by a voxel's measured or assigned attribute such as density.

Can I become a Facebook fan of the list ?
