CoronaRandomizer and Triplanar maps: what order?

[Tom]

Hi,

I'm a bit confused about the order in which to connect the CoronaRandomizer and Triplanar maps.

I've read somewhere that the CoronaRandomizer map must come first, then it has to be plugged into the Triplanar map, but I recently had the case where it didn't work and I had to plug the bitmap first into the Triplanar map, then into the CoronaRandomizer map.

Can you clarify this point?

Thanks

The correct order is map->randomizer->triplanar->material. I'm curious to see the example where reverse order gave you better results.

Thanks.
The thing is: in this particular case I don't care about randomizing the map, what I'm looking for is a way to apply a material on an object that doesn't have mapping coordinates, and at the same time I want to have the ability to shift the map on the Z axis.
So I use a Triplanar map for the first purpose, and then I add a Randomizer map to play with the Z Offset.

So my setup is: map > Triplanar > Randomizer > Material

Well, if it works in your specific case, then it's nothing wrong to use that map order, but i think you could achieve the same even without randomizer at all by shifting the map in bitmap node, or shifting UVs in triplanar itself.

But you can use it as you like as long as you are getting results what you are aiming for.

(...) or shifting UVs in triplanar itself.

Well I've never been paying attention to these settings of the Triplanar map actually, but you're right, thanks.
