Rotate bitmap texture

[billycoopdraws]

Hello,

I just spent the weekend beating my forehead bloody trying to simply rotate a bitmap texture in Corona.  Then I just came across this thread.

https://forum.corona-renderer.com/index.php?topic=35327.15  So am I correctly inferring I cannot simply rotate a bitmap texture in Corona, in the creation dialog in the node or material editors?

I am a 20 year vet using Revit, and I have been mainly using Enscape and Twinmotion for arch viz.  I want to dramatically up my game, so I subscribed....but it seems even the " easy" renderer in the Chaos family is anything but.  I know RTR's are toys to most of you here, but I have to start somewhere.  In the RTR's, the parameter to rotate a texture is completely and obviously exposed.  I am under critical pressure to produce excellent renders, and I am anything but dense, but just getting a simple texture and positioning it in this program has been an absolute nightmare for me. 

It seems to me Chaos could care less about new users, at least this is how this feels to me.  Every question I have asked resulted in an absolute quest to find answers, and now, at least on the surface, it seems I can't even rotate a TEXTURE? 

I hope someone on this team can restore my faith and sanity.  I am trying to learn C4D and Corona at the same time.

Help.

I feel your pain, but it's more a Cinema 4D issue than a Corona one.

For the longest time Cinema handles mapping at the material level, with the projection settings on the Texture Tag. It's handy with a pristine PBR material, but a f**** hell as soon as you want multiple textures with different projection settings (and buggy Projector shader everywhere ). It was fixed in the recent versions through the addition of the Node Editor ( the C4D one), but Corona doesn't use it.

So if you're using Corona 12 (latest version) you can convert your Bitmap to Corona Bitmap and use the Rotation W setting :



Or if you don't need to use the mesh UVs, you can use a Triplanar shader and it's Rotation settings :

Hi John,

I just checked into the forum before hitting the sack ( it's past midnight on the west coast of u.s.) .

I'm going to dive in face first in the morning...so I just wanted to thank you very much for contrib'ing and understanding.  To wit, one of the issues which has been very confounding to me has been UI pathing, which I understand will come with more time in the UI, But I do find things mildly confusing because I seem to keep losing my way depending on what parameters I select.  Your images seem pretty straightforward, so other than ranting, hopefully, following your breadcrumb trails some of this will clarify things, and I honestly appreciate the vine you've tossed in my direction to help pull me out of what started feeling like quicksand, for just a minute...

My very best to you.

You can also use a layer shader. Not ideal, but better than nothing.
There is also a free plugin which allows you to use several UV-Tags. (at least for older versions of C4D)

But it would be much better, if Corona would make a transform node for such tasks.
