One rendering image --> changing materials after

[Mario Pende]

Hi guys!

Is something like this available?

You render one shot of you scene and when its done you can later change color

of desired materials?

Thanx!

Maxwell offers such Plugin, can't remember the name...I don't think it can change the materials completely, like from diffuse to specular, but it sure can change colors.

 

In other renderers you can do this manually in post-production using material mask generated in 3D. E.g VrayMatID.

I thought Maxwell only had Multilight for different lightning solutions.

You are right, as was mentioned by Kippu I had "Swap" on my mind from Fryrender.

Found Motivia Colimo.

Seems very powerful!

[Derek Forreal]

Motiva Colimo does a great job. you can change colours, textures, UV scaling and more...

Derek, have you tried it?

[Derek Forreal]

yes, i use it with Thea Render. i use it mainly at the design stage as i can quickly and easily swap out materials to show clients scheme variations. you can also save lights so you can use it to change light colour/power and so on. it really helps with clients as they are often worried about committing to a particular tile, material or wall colour. and it also helps me a lot for the same reasons. it encourages me to experiment with different materials, colours and finishes and i see the result instantly rather than have to rerender and wait.

 

that's my main use but of course you can use it for a whole lot more.

[Mario Pende]

Is only Thea is supported?

This works in a way that you have to export an "image" from rendering engine, right?

Its not like exporting the whole scene...

[Derek Forreal]

it is directly compatible with Thea and modo as far as i know, but you can also render out the required pass(es) from any Mental Ray engine (so for example from Maya, Max, Softimage and so on).

 

and yes, you are correct, it works with 2d images rather than a 3d scene, so updates are instant.

is there something out there like this for vray and 3dmax?

In other renderers you can do this manually in post-production using material mask generated in 3D. E.g VrayMatID.

 

as said above, you could use render elements with your renderer of choice to separate the different objects and or materials in your scene and play with that afterwards in post production. and you could render only elements of your scene new... but of course, if you had a red floor in an apartment for example and you change it´s color to green now you would also have to change all the reflection and overall tint this material left bleeding around with your GI. but if the material does not bleed very much or you just want to tinker around a bit with the color balance or overlay another texture, you would be fine.

 

btw juraj, running into you all around the web lately, the vray multimatte element may work even better than vraymatid, have you tried that? it´s antialiased and works like a charm as you can select very easy it´s pure R/G/B channels in the photoshop channels with one click. and you can configure it to use the id of the material or the id of the object, very handy.

 

cheers,

not really. of course you can change a lot with PS but to think its the same thing is a mistake.

 

Colimo takes into account things like reflection and bleed automatically. so, as the example above suggests, you can change a bright red floor to a bright green one, and get the colour shift and response over the whole image.

 

but that's just the start. i used Colimo recently to present different design ideas to a client. the power isn't just in changing a flat colour, it's more in being able to swap materials, so you can quickly try for example swapping a wood floor for a different species, or for a concrete one, or a particular tile(s) and so on. you can adjust tile size (mapping), and rotation (turn a square tile 45deg for example).

 

honestly, in the early stages of a project it's an amazing tool. PS is good but it doesn't come close for swapping materials and changing light power, colour and so on.

 

just my 2c
