3Parts of Xpresso not updating when rendering on farm.
Any news on this? I'm trying to render an animated percentage counter, using an XPresso node data slider plugged into a Text Spline. When rendering on the farm with Deadline, I have the same error occuring, where some frames have no Text Spline. But, unfortunately, even the Redshift Render View is rendering this correctly, also the life viewport preview and viewport preview rendering, the final local rendering to PV is having the same missing Text Spline in random frames, as the farm. The Cinema version is 2025.1.3 and Redshift 2025.3.0 Any idea, how this can be fixed using just the given XPresso setup? We could bake this Spline as alembics, but this has a couple of drawbacks for text, like loosing shader assignments (C1, C2, S), baking several times due to hierarchy animations, etc.. Thanks. -
4Octane-Smoothing out fine details
Ah Mash, thanks so much for the explanation, that looks lovely and smooth on the inner, tho the outer has a bit of a line on it. I didnt realise my map was only 4000, left over from a previous attempt , thats a clever idea running the roughness only over the lettering tho I take onboard what you were saying about "perfect" glass. I think Im gonna redo the map at a larger scale and then duplicate what you have done here which should clean up the edge I think. Its my first ever use of an external renderer so quite a steep learning curve, but it is pretty awesome, compared to my previous ancient set up with just the C4D physical reneder for which I couldnt even use GI as it just killed my machines, this is a whole new world. Great to have members like yourself here to help us newbies. Many thanks Deck -

ok, main thing here is that sometimes too much detail is a bad thing. Your displacement map is a 2000x4000 image which is fine, but youve told octane's displacement to use a resolution of 8000x8000. This means the displacement is going to start showing the lower resolution of the image in the geometry. Lower the resolution of the displacement to 4k or 2k, then on top of that add in 2-3 pixels of gaussian blur below to give it a little more chance at being smooth. Next you can bump up the AA filter size a little. The default is 1.2 pixels wide, youll be fine with 1.3 or 1.4 Then I actually lowered the reflection depth down from 32 to I think about 10. Your letters are reflecting each other, making reflections of reflections. This wouldnt be so bad, but... ... your glass is too perfect. With 0% roughness you dont have glass, you have the most pristine diamond in the world. Ive taken the greyscale displacement map and piped it into the roughness of the glass, this way only the lettering will get a slightly rougher/softer finish. Its then dialled way back by setting the mix value of the roughness channel to 0.02 so it only affects it very slightly. This gets me from here to here3 -

Octane-Smoothing out fine details
Thanks Mash, email sent Deck PS, I did put in a tiny bit of roughness which sorted it out but that softens the whole thing, tho I could just paint that thru in pshop -

post a scene file or send it privately if you need ( mash@3dfluff.com ) and I'll take a look. dont forget textures The cause of the dark strip will be a reflection of a reflection of the sky bouncing between the letters but that doesnt explain the jaggedness
