I'm really new to Construct, I just purchased it recently and I have followed a few tutorials to get the hang of it and have set about making my own problem.
I've been using an art pack, and so when I imported my sprites and snapped my tiles to the grid I dismissed the problem as being down to the art pack initially when I noticed white seams between the sprites even though they should be perfectly aligned. Upon closer inspection, when I zoom in to look at the sprite, the image quality has been reduced quite drastically and it is quite blurry which seems to be causing the issue. I have turned on pixel rounding but it doesn't appear to have made a difference as I believe that only fixes rendering issues, whereas this seems to be an issue caused when importing the sprite.
The sprite size is 70x70 and I haven't made any edits to it in Construct.
Any help would be greatly appreciated, thanks a lot!
