Support

If you encounter problems with Piglet, please email me at "awesomesaucelabs" (at gmail).

Bug reports are greatly appreciated! If one of your glTF files is not loading/rendering correctly, please send an email with a description of the problem and a copy of your glTF file attached. (Screenshots are also extremely helpful.) I recognize that your glTF files may contain private intellectual property, but in most cases I will need a copy of your glTF file in order to troubleshoot the issue. I promise to keep your files private!

Contract Work

I am available for contract work, if you need specific Piglet features/fixes implemented by a deadline. Please email me at "awesomesaucelabs" (at gmail) to negotiate scheduling and pricing.
