The MP is the Marketplace. Sorry. I got used to the abbreviation talking with the other mods. Glad we could help, even if it wasn't in a direct way.

Also with the t-shirt, make sure the "include scales" is checked. It usually is for most newer things, but not guarantee

Please refrain from making unsubstantiated claims or accusations. Any more will cause this thread to be locked.

Try uploading an image again. I just did a couple of tests and had no problem. I recommend using jpg as they seem to upload best. Just keep the compression to a minimum so you don't lose much quality. And if you get an error message, please post that and I can message the developers.

I don't have a mac so I have no idea how to do that but here are some instructions that seem pretty straight forward. https://oit.colorado.edu/tutorial/clear-web-browser-cache-safari

I don't use Daz so I can't advise on that specifically. What I can say are generalizations I've noticed with the render engines in Poser and Blender, as well as a short stint with Reality. I'm also assuming that since you're a vendor you're hoping to get the best look without postwork since that's not allowed in the MP. In my experience, you need to have high enough render settings but things like proper lighting will help also. I've never seen these things being affected by the graphics cards. The only improvement I've seen is speed so I can use more lights or higher render settings and not have it take a long time. However, I also have to say that "a long time" is subjective. Switching from an 8-core CPU to an RTX 2060 for my rending makes things much faster in my book. It drops from hours or overnight to usually about 20 to 30 minutes. And I'm happy with that. But people with an RTX 4080 or 4090 will say my renders are so slow.

To be fair to ggreen, you did not give enough information in your original post to answer your question. What software are you rendering in? It's a Daz product so it's a reasonable assumption that you're rendering there, but there are bridges to other software and some people manage to get Daz products into Poser. What render engine are you using? What are the problems with your renders now? and rtx card may make your renders faster, but improve quality., it's hard to say.

Do you have the pro version (the one from the marketplace) or the one that was included with Poser?

JMCs are joint controlled morphs. Don't feel too bad about not being able to see those 178 results. None are for JMCs and are results for just the word control. You would have to search joint controlled morph to get results.

JMCs are morphs that are linked to the bending of a body part to allow for better bending. If you look at how your own arm bends at the elbow, you'll see how the flesh compresses and pushes out to the sides as your forearm presses against your upper arm. With 3D, they would just intersect each other. JMCs are a way to tell it to act more like a real arm and move the flesh around rather than intersect. Modern figures are also weight mapped which is a way to do similar without the morphs but there are some limitations so JMCs are still used for the most realistic looking bends.

I can't remember seeing one in the MP here, but I haven't seen everything here yet. If anyone has one 1971s would be the first store I'd check. https://www.renderosity.com/marketplace/vendors/1971s Many of their things have that feel. I'm not sure where else you'd look.

That's showing no lights, or lights the lights are all off and at zero position.

The issue you'd have to look at isn't so much the size of your image as the amount of stuff in your scene. If you do a lot of crowd scenes, you'll want more ram. If you usually do one or two figures, either would probably be fine.

I have 2060 12GB and usually can do about 10 figures.

agreed. Looks like L'homme

I agree. It looks like a lights issue. Usually when I see something like this, the lights were setup in a later frame but the scene is loading to the first. If I move to the end, the lights are fine and the scene looks right.

Zero out the morphs on the figure and post an image and we'll see if we can help you figure out who he is. Maybe in the future, if you save a morphed character with a new name, name him Will-(original name). Then you don't have to worry about forgetting.
