I’m using the 2024 version of sketchup and the 6.20.03 version of Vray. I’ve been with some bugs using this version of Vray. How can I download an older version? When I click the download button in Trimble area, it automatically begins to download the newer one, there is no option of downloading an older version of Vray.
You can always download versions of v-ray from Chaos.
However as @Anssi says, the latest version is the only version that works with 2024

That’s why I suggested you get in touch with Chaos Group’s Customer Support. As was pointed out, though, older versions of Vray won’t work with SketchUp 2024 anyway.
