That is very weird indeed, something you'd never think of (not me anyway, never use EXR). I'm curious what staff will say about the rendering itself, if they know.

Especially good that you found the culprit by yourself!

Extremely cool, especially the last POV, with the great variation in hues and darks. Very subtle. Did you use (a.o) the water shader for sand displacement? I actually never thought of using a lambert shader for surfaces like this. I guess the translucency and the PT light reflections give it such a subtle 'gloom'.

Image Sharing / Canyon series 1

A series of canyon's I've been working on...

Little fun fact; there's only one lambert shader as surface shader (w/o translucency and w/o masks).
The sand has the same colour, though ever slightly lighter with fake stones (which uses built-in RGB colour variation) as sand grains.

OK, I think I've found the problem and it's strange.  ::)

But first, it's important to know that these invaders (which is what I'm calling them -- they remind me of old Space Invaders sprites) didn't appear until the foliage was added to the scene. Then they showed up in every render, but in different locations each time. Sometimes over foliage, sometimes over water or elsewhere. (I even rendered the same file on both machines last night and yep, they showed up in both.)

While loading the file I finally noticed this error. It was getting thrown each time TG attempted to load a displacement file associated with one of the trees:

FreeImage error: Warning: loading color model R as Y color model

So I looked at the file, which came with a Megascans bark shader. It was an EXR file and had a single channel (which appears in Photoshop's layers panel) named "[R]". All other EXR files in the scene have a single channel named "RGB".

FreeImage must be the library module that TG uses for EXR support. This page explains the problem: https://sourceforge.net/p/freeimage/bugs/283/. More detail here: https://github.com/imageio/imageio/issues/356.

Anyway. I just changed the channel name in Photoshop from "[R]" to "RGB" and resaved it. The error went away and (fingers crossed) the render currently running looks fine so far. Why this would have anything to do with the renderer is beyond me. But the problem seems to be fixed: No more invaders. I'll be doing nightly renderings so if it hasn't been fixed, it will show up again soon enough.

Image Sharing / Nice place for R&R

Hi all ! I changed the camera to get a closer look at the chalet from the previous post with everything else kept the same. This was an exercise in precision placing of plants for the rocky base, the wall, the flowerbed on the wall as well as border trees. One spruce was a bit too close to the camera on the left but saw it only well into the render. The fireweed was made from scratch in XFrogs years ago and turned out fairly well for this image. The render was done with the standard renderer and eager to see if the RT gives better vegetation. The chalet was purchased in CG Trader if I remember correctly. I made the windows are a bit too transparent and in some areas show an empty house with wooden wall..... will tone that down and put more reflections..... or maybe buy furniture ! Take care and have a great weekend !

They will see it, and respond. Perhaps (if it takes too long) state the same question at the discord forum.

Looking forward to see anything you're working on, always a treat! And knowing more about your new way, if you care to share.

I'm hoping someone from Planetside might see this and let me know what these are. I wonder if they might indicate a hardware problem, though I've run across them on two very different systems. I'm running a memory check now on the system that I used to render this, just to see.

And thanks re: the trees. This is the top part of a new scene I'm working on. Once I have something more presentable I might post it here. I'm testing a new way to create historically accurate landscapes . . . seems promising. As far as the forest goes, it's still too tidy. Needs some windfalls and dead trees, more undergrowth.

I can't help you here; never had these and I wouldn't know what could be blamed. Must be something in the renderer itself, I'd say, not any setting. Nice trees in the background by the way.
