Cant import usd file correctly from blender exported file

I created a plant in blender and export it as a usd file. When i import it in isaac sim ,some wrong happened,it said"Requested type double for stage metadatum metersPerUnit does not match retrieved type float",what the problem?


Can you open your usda file and check the metersPerUnit? usda is usd in text form. Blender might be able to export usda or you can use this command as showed here

usdcat file.usd --out file.usd --usdFormat usda

You can also open our robots like Franka, save it as usda file to see the metersPerUnit should look like this.
metersPerUnit = 0.01

Thank you for you answer, I exported usda file and imported in isaac sim,it works.
