I took the adjusted files cs3_08f.ymap and cs3_08f_critical_0.ymaped that you have shared and I have increased the streamingExtentsMin and streamingExtentsMax as you have indicated and I also increased the lodDist value from 601.00000000 to 5001.00000000 and now the problem was GONE!!! Finally!
I had to replace the files in two locations as you can see in this image: https://drive.google.com/file/d/1zewx2PAOQVNgPqxgC6j31wu5d2w6sxsF/view
I got a shot from far from the tree (as per this image):
And for my surprise,, when I ZOOM into it (from that distance), I got the following:
P.S.: Sorry, i have registered in Flickr but I don´t see the IMAGE URL to share here and easily show the image.
I also uploaded a video to youtube demonstrating the final result (i used a different timecycle without FOG in order to allow a better visualization - sorry for the clouds).
If anyone wants to download the files that I edited with the adjustments you mentioned, here is the link to download them: https://drive.google.com/file/d/1ZRW7cE1mTxrr9N6ndv7GYji10lRGgTK7/view?usp=sharing
In regards to the Prop_Bush_Lrg_04 in the region you highlighted, i will try to also replicate the issue and begin analyzing if I solve it (i promisse to share if i do, but i am sure it will take time).
It is a pity that we have to locate all YMAPs and punctually make this adjustments in everysingle LodDist in order to fix the issue with this tree but, anyway, that´s the way GTA V was created.
Man, I thank you very much for your support and patience here! It´s SOLVED!!! I am quite sure that this TOPIC will help a lot of GTA modders and players!
