If you ask; the latter, vertical one appeals most to me, because of the contrasts. PT has 'trouble' with tiny displacements+reflection, that may be the 'problem'. But even a very small PT render will show the differences, I'd say.

Quote from: Dune on March 26, 2024, 02:34:21 AMThanks Martin. Interesting fact about the cache detail. I wonder how it would look in PT.
Welcome!
Yeah me too, but somehow it's crazy slow with PT. I might try Thursday overnight since I won't need my PC until Friday noon.
Which one should I choose you think? I probably can't render it bigger than 1280 wide/tall.

QuoteIf you like, can you share an .exr which exhibits this behaviour?
Hi Martin -- The EXR file is a commercial file from Megascans . . . but I bet it wouldn't be hard to make a generic file that would trigger the error. Now, I think the error is benign (or it simply cancels any displacement or bump). At any rate it's probably not related to the artifacts as I first thought. But let me get back to you.


QuoteThis could an image filter problem where a sharpening filter produces negative pixel values. Try using the Cubic B-Spline filter, it might help.
Pokoy -- This makes sense. I can see how a filter might be the culprit. I've always used Mitchell-Netravali. 

For post effects, Soft Clip Effect, Compensate Soft Clip, and Contrast (0.25) are all enabled. I believe these are the default settings. (Up until recently I always rendered straight to EXR and did not worry about the Tonemap tab. But I've started rendering to 16-bit TIFF because they import very nicely into Lightroom. So now, it seems, these settings are applied.)

It's probably best to try one thing at a time. I'll start by setting the filter to Cubic B-Spline.

Thanks!

Image Sharing / Beautiful tufflandscape

I found a very beautiful new texture. Texture to make tuff-landscapes.
Webside: iStockphoto.com   Searchword: tuff or tuff texture . . .
(Texture is expensive but very beautiful and useable)

Also, are you using any of the Post Effects? If so, they might not clamp values below zero produced by image sharpening and result in strange artifacts.
In any case, using a soft filter might help to sort this out.

Intriguing issue, but annoying for you for sure.

If you like, can you share an .exr which exhibits this behaviour?

They're back. I thought last night's results might be too good to be true. One artifact has appeared so far in the rendering I started this morning.

The FreeImage bug is real, anyway. Good to know that. As far as the Space Invaders go, I'll wait to see if anyone from Planetside pops in here. If not I'll contact them by email.

Oh... an update... looks good, but the house is too dark (texture illumination set to 1.0, like at the plant tut?)
And Ulco is so right, more bushes would be  great!
