Maya place2dTexture issue

MtoA 3.3.0.1, Maya 2018/2019, Win10

2d texture placement has some issues in the latest mtoa versions. I make plane with uv shell 0-6, assign simple red-green ramp and disable wrapping in place2dTexture node. I expect to move it across the surface with translateFrame/coverage and other placement controls... It worked properly before (MtoA 3.1.0.2):

But now (3.3.0.1, 3.2.1 is even worse) it gets cut by 0-1 boundary and repeats inside:

hi, use this osl insted.

https://github.com/devRND-ess/aiShader_osl_probabilityPosition/blob/master/rampCustom.osl

actually your ramp is behaving as it should right now, cause it goes from 0 to 1 and then again 1 to 2 and so on..so i just created this osl shader and it doesn't use uvs so you can utilize this if ramp was only what you wanted....

you can use it with mix node for textures and color. else tell me I can implement that as well......

Thanks for the effort, but maybe I wasn't clear enough in my description... You can't move ramp outside 0-1 uv space anymore with wrapUV turned off. Check this example in MtoA 3.3.0.1:

While for years before MtoA 3.2.x everything was fine. Here's the same scene with MtoA 3.1.2.1:

That's clearly an issue in the latest arnold versions and that doesn't seem like a good idea to update people and farms and dozens of assets with custom shaders because of that.

Yeah that's an issue ....you should raise a ticket for that...so that it gets resolved in the next update....or if someone else knows any solution to this(if it's not a maya issue) would be happy to know...

Ticket? I thought posting a problem here is enough for developers to see it and take into consideration... Or not?

[sharmabhuwan14]

not sure of that..even better if they see it here and gets resolved........
