Is it better ?

            if (cmd.hasProjection()) {
                val proj = xbuf.cnv(cmd.getProjection(), new Matrix4f());
                cam0.setParallelProjection(cmd.getProjMode() == ProjMode.orthographic)
                if (cmd.getProjMode() == ProjMode.orthographic) {
                    val lr = pairOf(proj.m00, proj.m03)
                    val bt = pairOf(proj.m11, proj.m13)
                    val nf = pairOf(-proj.m22, proj.m23)
                    cam0.setFrustum(nf.key, nf.value, lr.key, lr.value, bt.value, bt.key)
                } else {
                    val fovY = 2f * FastMath.RAD_TO_DEG * FastMath.atan(1f / proj.m11)
                    val aspect = proj.m11 / proj.m00
                    cam0.setFrustumPerspective(fovY, aspect, cmd.getNear(), cmd.getFar())
                }
            }

As long as you don’t use Camera.setProjectionMatrix() its fine.
