I apologies if this should be in the bug reporting, but thought this may be something I have done wrong!

I have a high poly scene (8M Polygons and ca. 450,547 KBytes) of a house and garden with lots of Cosmos proxy trees and plants. Since running Corona 10 (first daily build) I have seen just the tree textures (mainly bark) in this model to render very low resolution. I have attached two images, the first is a render of just a Scots Pine Proxy with 2 render instances at different distances from the camera (Trees look fine) and another with the exact same tree imported into my model of the garden (now low res). Both scenes have identical render and lighting setups and rendered using Corona 10 daily build from June 20 2023.

I have tried the following:
Deleting the Scots Pine model from the Cosmos libary on my PC and redowloading it and replacing the models in my scene
importing the entire scene into a new file
Importing one of the Scot's pine trees into a new file
Creating a new Corona physical material using the original texture files
Creating a new Corona physical material using textures from my own library

All attempts end up with the same low resolution result. Has anyone come across this before or can tell me what I am doing wrong?

I am running Cinema 4d 2023.2.2
Renders were done to 1920 x 1080 with 10 passes (test renders) and no denoising. All other Corona settings are default with only bloom and glare set low in the camera. No DOF or camera animation either.

Hi there, Cosmos assets are downloaded with various ''qualities''. Do you have the correct one loaded? The high-quality mesh is labeled ''3dh'' and the low version is ''3dl''.

Hi Beanzvision,

I have just checked and I have the 3dh version in both scenes.

Okay thanks. Are you able to share your scene with us at all? If so, please use the link in my signature below. Thanks in advance.

P.S. Feel free to strip back the scene if need be.

Hi there, can you try lowering the blur scale to -100% and let us know the outcome?

Will have a go at that before sending the scene.

Same result I am afraid. No improvement of the texture in the render. Test render is attached.

The scene is being sent to you via the 3D Support link in your signature, for your attention. The uploader didn't work for me.

Thanks for letting us know. I think we will need to investigate the scene further. You can also create a support ticket and share the scene there if it helps.

Can you also try turning off ''out of core textures'' to see if this helps?
