Step-by-step guide to fixing warped T-shirt mockups in Bulk Mockup using nested Smart Objects, merged layers, and clean templates for fast, consistent exports.
hey Nat thank you for sharing the files I could do you know let me open the template and I will
get to know the issue that you have so this is the placeholder which looks nice but if I double
click and open this this is your problem okay so again this is a smart object layer here okay so
this is the file that we had sent you so the problem is what happens is
I’ll show you how the best way to process it and then we will see so basically when you do this
what happens is bulk mock -up opens up the smart object layer and then it places the design over
here in this place which actually you know it has been made up to fit your t -shirt okay so it opens
up and it places the design here and when we do place the design here it is placed in a straight
way and when we do this this happens so either there are two ways to fix this okay let me close
this one double click and instead of placing the design here we’ll double click and open it once
more and then we can place our design here and in the meantime we can all if you do this it looks
broken and now this places this is placed perfectly okay so if you want to use the same arrangement do
not want to mess up your file it’s easy to do I will have to use bulk mock -ups nested smart object
feature so to use that just rename this smart object layer as add design so when you rename it add design
bulk mock -up will open this and now this again is a smart object layer so we’ll rename it as nested so
this is the nested smart object layer if bulk mock -up encounters this nested smart object here
so instead of placing the design here it will double click and open it up and then place the design here
so that is how it works and I believe this could give you some trouble because there are multiple layers
so what I’ll do is I’ll go ahead and select all the layers and press ctrl e to merge all of them okay
so do this on all your templates merge all of them because we want our placeholder design to be placed on the top
now now this should work properly so this is one setting that you could take the other way around
would be to recreate I’m not sure if you created it yourself or you use somebody’s help so again this
has the same arrangement so either to fix it at design
at nested and that’s all good so sorry select all save ctrl e to merge it and save it so this is how it
goes the other way to fix it would be let me show you so I’ll take this as a design file
placeholder text
so I’ll close this
so I’ll open another t -shirt and delete this
now I’ll grab the placeholder design
when I place it it’s actually placeholder here
now whatever warping I’m supposed to do I can do it here
so if you’re using the placeholder then you can do like this
this one and then right click and warping
I’m not very good with this but yeah so this is the
you make a adjustment over here so this will again be straight and whatever adjustment we do
we do on the first layer itself so all the settings will be applied here so this is the other way to
get around this okay
In this case, the user experiences distorted and broken artwork when exporting T-shirt designs through Bulk Mockup. The issue comes from how the template’s Smart Objects were set up, especially because the design is supposed to sit inside a nested Smart Object.
Bulk Mockup opens only the first Smart Object it encounters—so if the placeholder is incorrectly organized, the applied artwork appears warped.
Follow these steps to fix the issue completely:
This nested structure is the root cause of the distortion when Bulk Mockup processes the file.
Bulk Mockup must also place the design here, not in the outer Smart Object.
To force Bulk Mockup to navigate deeper:
Bulk Mockup will:
→ detect @design
→ open it
→ see @nested
→ open it
→ place your design correctly inside the warp-ready canvas
If the placeholder contains multiple layers (text, effects, graphics):
This prevents Bulk Mockup from misreading multiple Smart Objects and ensures the warp shape remains intact.
Your designs will now follow the correct warp curve without twisting, stretching, or looking broken.
Rename the main Smart Object to @design, mark the inner one as @nested, merge placeholder layers, and Bulk Mockup will place T-shirt designs without warping or distortion.
This happens because Bulk Mockup is placing your artwork in the wrong Smart Object level. If the warp or distortion exists only inside a deeper Smart Object, Bulk Mockup must be guided to place the design inside that nested layer, not the outer one.
Bulk Mockup recognizes specific layer names— @design and @nested. Renaming layers instructs the plugin to go deeper into the Smart Object hierarchy so that your design is inserted exactly where the warp or transformation is intended.
If a placeholder contains multiple layers, Bulk Mockup may struggle to preserve the warp integrity. Merging them into one layer using Ctrl + E ensures the software sees a single distortion map, improving the final design placement significantly.
Yes. You can manually warp the placeholder artwork by placing the flat design directly onto a mockup and applying Transform > Warp. This method avoids nested Smart Objects entirely and preserves consistent warp behavior for all future designs.
Absolutely. Any template with curved, wrinkled, or distorted surfaces may use nested Smart Objects for realistic warping. The same renaming and merging steps ensure Bulk Mockup places artwork correctly across all apparel types.
