can a ramp option be added to the emitter to controll light intensity and colour. Making and always changing a MXI/HDR file takes way to long. Using a ramp would be much faster and give you alot more controll.

I hope to see these implemented in the next update.

Why not use multilight instead?

here is an example of what im after. this was done using Maya and mental ray.

mulitlight would not give the same amount of controll.

OK this is already possible with MXI/HDR texture but is it possible to alter this gradient realtime in above examples?

[cream]

Yes you can do everything realtime, thats whats what makes it so much better then a MXI/HDR file. Also this way you can put in exact values eg. (3.5 - 1500)

all that is happening is the intensity value in the emitter is running of the ramp values. it should be very easy to add.

While saying "realtime", I meant altering values while rendering on-the-fly. I guess you're just asking for procedural textures, then. Technically it's what we call this. Gradient Ramp is a procedural texture item and they are not yet available with Maxwell.

i think that´s what he meant...
but even with procedurals for light colors you still have to generate uv´s for the emitter geometry, so it wouldn´t be much faster than with mxi i think...

You know, emitters are not only made of plane geometries, so this is reasonable enough.

[Rickyx]

Good idea but... I think a mxi file like this will became so unreasonably huge to be impossible to use and store:
it should store the provenience of the single raylight, like a micro emitter...

Yes procedural textures is the word i was after. It would be great to see a basic ramp procedural in maxwell. It would make life so much easier then always having to make a new MXI.

In Maya you dont need to creat UVs on a plane as they are already there and are how i want it. So being able to create a procedural textures and edit it on the fly would be heeps faster and more accurate then using a MXI.
