Triplanar - Object/world space texture sliding

[stir]

Hi

It looks like the triplanar Object space and worldspace coordinats is broken.
They both act the same unless i misunderstand how they are suppose to work.

This is how i think about it.

- You create a sphere in your 3ds max scene.

- You animate it from left to right.

- You apply a triplanar texture map to it and pick Object space.
This should make the texture stick/lock to the object.

- You now change it to worldspace
This should make the texture slide across the sphere because the sphere is animated.

At my end i get sliding on both systems.

UNLESS!!!!
I check the movable proxy on the sphere, then object space works as it should.
Is that intended? Do i really need to make all the objects containing this triplanar material to be movable proxy to make it work correctly?


They are both objectspace in the triplanar - But the first one is movable proxy and the second is not.

Hi Stir,
my animation test seems to works fine, could you share your scene please?

Here Paride

I have attached the maxfile in this post.


Here is the renders i made with this file, just for references to see if you get the same result.

Here is frame 0 and 5, the sphere DON'T have movable proxy on.

Here is frame 0 and 5, the sphere DO have movable proxy on.

specs:
3ds max 2019.3
Octane 4.01.1 - 6-12
Windows 10 64-bit
Nvidia 1080ti x3

Hi Stir,
you have not to put triplanar map into RGB image node.

Sorry paride.
It still doesn't work.

I have made a new test scene, this time i have based on this
https://docs.otoy.com/3DSMaxH/3DSMaxPlu ... narMap.htm

So we dont need to complicate it with maps, only colors.

The results i get:

Movable proxy off

Movable proxy on

The sphere is here animated between frame 0 and 5 with a 90degree rotation in Z
And the triplanar shader is set to object space on all the renders.

I would really appreciate it if you had time to take a look on this maxfile aswell.

Thanks for the help

I've had this issue in the past. If I recall correctly, you have to turn on movable proxy(which is un intuitive).

Indeed, that's what i am trying to say.
And it is really strange.

Hi guys,
if you want to see the textures rotate coherently with the moving object, you must use movable proxy option.
you must use movable proxy option with all moving objects in the scene, and personally my advice is use movable proxy always and anyway.
A correct animation is object-space and movable proxy; if you want special effect you can use word or object space, but using projection node too.

Sorry for late reply.

Thank you for clearing that up Paride.
I was under the impression that movable proxy was only needed for quick previewing.
But I will follow you advice and always use movable proxy on animated objects from now on.


Good to know
Thanks

HI, sorry this is an old thread but when looking for triplanar swimming issues this is the only that came up. Is there a similar fix for the Houdini plug-in? I have all of my triplanars set to Object Space but they still slide around on moving objects.
