The four blocks (red green blue) are not coming while the render is on is directly rendering the image in my sketchup pro 2021 please help
Share the SketchUp file so we can see what you are working with and a screenshot from Vray.
Please correct your forum profile. There is no SketchUp 2021 Free Plan.
As I wrote, share the SketchUp file so we can see what you are working with.
And fix your forum profile.
Your screenshot gives us no idea about what we should be seeing inside the area you circled where the render is in progress. We just see some trees that look OK.
Did you activated Progressive?
Or did you switch to Render with V-Ray Interactive?
Or did you somehow change the size of the buckets?
I second what @mihai.s recommends - check your Render Settings in the Asset Editor and make sure that Interactive is disabled and Progressive is disabled.
