wanted to reply here on your rather harsh review
I do my best to show the assets as close to what you get, I show images of different looks, i show a lengthy video or demo, so you see how the animation looks (using the exact same images included in the pack) and additionally you can check exactly what images you get in the product filebrowser. I cannot make what you think it will look like..
so i just find it strange you call it ugly and jumpy, as everything is clearly shown, i cant help thinking you are using it wrong, you can get the exact same look in construct2 as shown in the demo.
The double exhaust was the initial & only look, I added the other one on request, and added an example of it, (yes by modifying the original) if that strikes you as lazy, then so be it
anyway, for anyone having trouble getting the same look as in the demo, im always happy to help
furthermore one of the reasons I made these, is the ability to produce the exact look as in my ship presentations but within construct2, with particles system this is hard to do, I already used the same animation in my launchplatform recently and i quite liked the result.
