Construct 3 preview take very longer time compared to Construct 2.

I brought my licence today and ported my project to c3.

Everytime I open and preview my project it take long time to process a spritesheet (in picture below) that when i use construct 2 it take much faster to preview my project. But once it complete it can preview fast without that process until i close construct 3.

Is there anyway to skip or disable this spritesheet process or make it save its optimized spritesheet somewhere for faster preview.

Thank you.

The "Preparing images" step only needs to be done once per session. It may be done again if you change many images in your project, such as Sprite animation frames. If it does it repeatedly despite no such changes being made in the editor, it's probably a bug, so please file an issue about that.

Thank you for support. I use construct 3 in Microsoft Edge and install as an App. Does "done once per session" means every time i closed bowser it Must do again? or Does Edge had auto clear session when close that i should not let it clear?

It means once after opening the project. It remembers the prepared images for open projects. If you close the project and re-open it, it will do it again; if you close and reopen the browser it will do it again; but if you do something like change an object property while keeping the project open, it shouldn't do it again.

Thank you Ashley I understand now. May i ask if there will be an option to preview without that process in the future? Just like Construct 2. My project take very long time to preview now and i am afraid it will be pain if my project is bigger in future. Thank again for your great support.

I'm afraid it's not possible for Construct to preview your project without preparing the images. Construct 3 uses an in-editor spritesheeting system which is why it must prepare in the editor, where Construct 2 only did it on export. Since C3's release in 2017 I've not heard of it being a serious issue at all, especially since it only has to do it once after opening your project. It's not doing it every preview, right? Just once after opening, like I described?
