Are there discrepancies in relative sizing compared to the stock behaviour? I've not meddled in this to the point of introducing such disparity...
Never seeing that word (discrepancy) and using translate, I guess the answer is no
I tested a stock version of the game (4.12) and the big guys also have the same explosion. A big puff of smoke that is
I remembered Dave's realism effects had some good big explosions for the heavy bombs, and indeed here they are
2000kg on the left, 2x 1000kg on the right
They are indeed the same but they look good for bombs this size
Seeing how little choice you have, I can only recommend going for a similar effect for the Bomb1000
Interesting about the delay on the bigguns causing a reduced effect size. I suppose it could be a means of representing the partially braked explosive power due being buried?
Yes, as that has been implemented in 4.12 but I think a 5 ton bomb would blast a ton of smoke and dirt into the air regadless <- now that made me remember that even in stock game with stock effects, the fab 5000's explosion looks tiny even with a fraction of a second of delay
But then I don't know how much control you have over delayed explosions
