I'm going to get into the crux of the matter.
I have a lens that's >8 MB, and I don't want to lose anything from the work I've done.
1- If your lens has a lot of mesh 3D. You need to change it from float to half float, it won't affect anything in your project
2- Compress images, many do not know about this that the project images or images are like grain. Its size is large, which leads to an increase in the size of the lens.
We will reduce the size of the image without changing any quality by a small difference so that he does not see a difference between it and the average
We will need a website to reduce images online
We will change the images in the project
We will apply this to all the images and we will see the result
I wish you good luck
