Hi @KYO_WA,

 

Thanks for the question.

 

Due to how graphics processing hardware performs its computations, all the assets in the graph have power of two dimensions.

This is also why the final outputs are always 2048x2048, 4096x4096, etc., and not random numbers. Therefore, when you import a bitmap, it will have the same restrictions, and Substance Designer will stretch the image to fit the closest power of two.

 

With that being said, it's perfectly possible to have a non-square ratio imag

With that being said, it's perfectly possible to have a non-square ratio image. In the Output size parameter of the node, change the Width/Height value in order to get a rectangle. As long as your bitmap isn't natively a power of 2, the image will always be stretched, but it can help making it less obvious.

I advise you to take a look at our documentation on the subject, I'm pretty sure this will interest you.

お返事ありがとうございます。 出力サイズを変更することで対応できることを理解しています。 だから問題は、出力サイズのピクセルのアスペクト比を自由に変更することは可能ですか? また、インポートされた画像の比率を変更しない方法はありますか? 今回のように画像や動画で説明してください。
