Hi eLaCiD,
I have a licensed copy of Twilight Pro, & all their add ons I paid for too, Fast Forward Denoiser, Render-to-Texture, Render Terrain, but what you are asking is not possible.
I’ve used twilight for 10yrs and was in the same boat as you and spent a ton of time trying to get my own licenses working again. I had to upgrade my computer and had a new install of windows but your license is tied to the original windows install of when you request your activation code. So even tho I have my license code and activation code they don’t work.
In my free time I have been trying to decode using debugger tools how that code is generated and have made some progress there are a few areas in your registery that twilight looks up to generate the number. I found 2 but not all of them.
Anyway I spent 3 weeks on that before it forced me to try new programs, I tested a bunch. The one I landed on is D5 Render which is pretty amazing, very happy with it. Twilight does have a specific look that I love though and I do still want to get working some day but it’s way less of a priority for me. Send me a DM if you want to continue what I’ve been doing, and I can fill you in.
I also have almost every version of twilight saved and I did get the last version to work on sketchup 2024 and now 2025. See this thread and my message of how to do that.
Goodluck!
