Mix HDRI loose orientation

[Flcc]

Hi

For a specific film I need to smootly switch between HDRI envitronements.
I use "Mix textures" in place of the image texture channel. This works but Orientation don't work anymore.
Neither the RotX paramater nor the Sky object orientation.

Is this the normal behavior ?.
Or am I do something wrong ?

is there a workaround ?

PS : I use latest 2.23 stabile

Yes sure. Plugin internally creates a transform when you have just an image texture. Try to create transform node under images if you make different setups.

Yes, using T.X under UVW transformation Works !
I can connect them to an xpresso and Animate them independently

Thank for the quick response

And if i can ?

Actually I need more than two HDRI maybe 4 or more if i can. (Its for an oniric cosmetics products film).
Have you a better workflow idea than put mix textures into Mix textures ?

Thanks anyway !

I'm not sure that's a good idea to mix 4 hdri. Maybe a performance loss or issues on render. Need to check.

No need for four HDRIs in the same time.
Maybe i'm not explain very Well.
The need is to play with 4 or more (if i can) HDRI env, like play with differents sets of lights.
What i search is an "ergonomic" way for play with HDRs. Sort of making a VJ mixer.

Would a gradient mixer work in this case?

I'm new to Octane, but this seems like it might get you on the right path.

Hi,
I hope it could be useful, at least it was useful for me for refreshing XPresso
Here is a modified Environment node via Xpresso that let you choose between 8 different textures for a total of 4 HDRIs. Then you can rotate them separately and mix them together:

Thank you guys for help

@niestudio
Really helpfull link. I didn't know the complex mode of the gradient.
In my case I think it don't do the trick. If you want fade between tex1 to tex3 you can't avoid tex2.
But may be really usefull anyway.

@bepeg4d
Thank for the file.
It's nearly what i did, but with a more usefull setup.
But this way we can' avoid the "double master".
It's like a 2x2 channel Mixer.
What i try to do is a 1x4 channel (or more) Mixer.

not really different, but in terms of animation give more freedom. More simple handling
Sorry my english skills is not very high and it's not easy for me to clearly explain the reasons.

May be a trick to find... with the gradient ?

Thanks anyway for the help.

Helpful trick - c4d reading only the top HDRI in the object manager hierarchy. So when exploring lights i׳m loading bunch of HDRIs to my scene and just grab each on up everytime i want it to effect.
